# How EchoZero works
Source: https://docs.echozero.app/concepts/how-it-works
The runtime loop from your strategy to subscriber execution and developer payouts.
EchoZero connects **off-platform signal sources** (your bot, TradingView, Telegram/Discord groups, or a custom HTTP integration) to **custodial execution** for marketplace subscribers. You publish an agent; subscribers opt in; every accepted signal can fan out into per-subscriber trades, fees, and weekly payouts.
## The runtime loop
```mermaid theme={null}
flowchart LR
A[Your strategy / bot] -->|signal| B[EchoZero ingest]
B --> C[Parse & validate]
C --> D[Custodial execution]
D --> E[Per-subscriber fan-out]
E --> F[Fees & ledger]
F --> G[Weekly payout / claims]
```
1. **Your strategy emits a signal** via webhook (`POST /api/public/agent-signals/{id}`), WebSocket (`/ws/signals`), Telegram/Discord (signal-group agents), or the developer API.
2. **EchoZero ingests and normalizes** the payload into a common envelope (natural language, structured `#1098` JSON, or legacy `action` + `tokenAddress`).
3. **Execution bridge** resolves tokens, trade size, leverage, and subscriber eligibility. Virtual wallet mode uses simulated balances; live mode routes to Solana spot or Hyperliquid perps.
4. **Fan-out** runs per eligible subscriber (subscription, channel membership, wallet mode, geo rules).
5. **Fees** accrue from success fees and/or subscriptions. Developers claim balances or receive Stripe Connect payouts.
## Surfaces you integrate with
| Surface | Best for |
| ---------------------------------------------- | ----------------------------------------- |
| [Inbound webhook](/guides/webhook-security) | Server-to-server bots with per-agent HMAC |
| [WebSocket gateway](/guides/websocket-gateway) | Low-latency streaming from your engine |
| [Signal groups](/guides/signal-groups) | Telegram/Discord channel operators |
| [REST API](/quickstart) | CRUD, wallet, sandbox, earnings |
| [MCP](/guides/mcp) | AI assistants (Claude, ChatGPT, Cursor) |
## What happens to a signal
| Stage | Output |
| ---------------- | -------------------------------------------------------------------------------- |
| Accepted | `outcome: matched`, `signalId` assigned |
| Parser miss | `outcome: unmatched` or `skipped` with `skipReason` |
| Feed-only events | `trade_idea`, `position_update`, `trade_review` post to activity feed (no trade) |
| Execution | Optional `signal.execution` callback to your `webhookUrl` |
## Agent must be live
Signals are only processed when the agent is in **`beta`** or **`public`** status. New agents start in **`pending-review`** until approved. See [Agent lifecycle](/guides/agent-lifecycle).
## Next steps
End-to-end tutorial: create agent, send a signal, see `outcome: matched`.
Agents, strategies, signals, subscribers, and fees defined.
# Core objects & glossary
Source: https://docs.echozero.app/concepts/objects
Agents, strategies, signals, subscribers, and the terms you will see across the API.
EchoZero uses a few core objects. This page defines them and how they relate.
## Entity model
```mermaid theme={null}
erDiagram
Developer ||--o{ Agent : publishes
Agent ||--o{ Signal : receives
Signal ||--o{ Trade : may_execute
User ||--o{ Subscription : holds
Subscription }o--|| Agent : follows
Agent ||--o| Strategy : may_use
```
| Object | What it is |
| -------------------- | --------------------------------------------------------------------------------------------------------------------------------------------------------- |
| **Developer** | Registered builder with API keys, Stripe Connect, and payout rails |
| **Agent** | Marketplace listing that receives signals and fans out to subscribers |
| **Strategy** | Automated trading bot configuration (risk rules, conditions). In API copy, *strategy* and *trading bot* refer to the same resource (`/api/v1/strategies`) |
| **Signal** | One inbound trade intent (`TradeSignal` row) from webhook, WebSocket, Telegram, Discord, or API |
| **Subscriber** | End user with an active paid or free subscription to your agent |
| **Position / trade** | Executed buy/sell row tied to a subscriber wallet |
| **Success fee** | Percent of profitable trade notional charged to subscribers on the success-fee model |
## Agent vs strategy
* **Agent** = marketplace persona + signal ingress + subscriber graph.
* **Strategy** = bot logic for automated trading on EchoZero (conditions, risk management, pause/play).
Signal-group and webhook agents focus on **ingress + fan-out**. Strategies are optional automation layers subscribers can also run.

# Agent lifecycle & listing
Source: https://docs.echozero.app/guides/agent-lifecycle
From draft to pending-review, beta, and public marketplace listing.
Developer agents move through review states before they can accept live subscriber execution.
## State diagram
```mermaid theme={null}
stateDiagram-v2
[*] --> pending-review: Create agent
pending-review --> beta: Admin approve
pending-review --> rejected: Admin reject
beta --> public: Admin promote or 30-day auto-promote
rejected --> [*]
public --> [*]
```
| `betaStatus` | Signals accepted? | Marketplace visible? |
| ---------------- | ----------------- | -------------------- |
| `pending-review` | No | No |
| `beta` | Yes | Yes (beta listing) |
| `public` | Yes | Yes (full listing) |
| `rejected` | No | No |
## Creating an agent
`POST /api/v1/agents` with your developer API key. New marketplace agents typically start as **`pending-review`**.
Include `signalSourceKind`:
* `webhook` for HTTP ingress (returns `inboundWebhookSigningSecretReveal` once)
* `signal_group` for Telegram/Discord (see [Signal groups](/guides/signal-groups))
## Review workflow
Platform admins use internal review endpoints to:
1. **Approve** (`pending-review` → `beta`): requires `safetyScore` and notes
2. **Reject** (`pending-review` → `rejected`): requires rejection notes
3. **Promote** (`beta` → `public`): moves agent to full marketplace visibility (admins can also promote manually at any time)
Agents in **beta** auto-promote to **public** after **30 days** if not rejected. The `betaStartDate` field records when beta began and is used for that window.
As a developer, poll your agent:
```bash theme={null}
curl -sS "https://mcp.echozero.app/api/v1/agents/$AGENT_ID" \
-H "x-api-key: $EZ_API_KEY"
```
Check `betaStatus`, `betaStartDate`, and `latestReview` on marketplace responses.
## Reasoning and safety
Structured signals require `reasoning` (1-4000 chars). Feed safety filters may reject signals with banned content. Strong reasoning and consistent signal quality improve review outcomes and are **required to promote agents to live** public listing.
## Going live checklist
1. Complete [Stripe Connect onboarding](/guides/earnings) if you charge subscriptions
2. Set pricing (`pricingModel`, `monthlyPrice`, `successFeePercent`)
3. Configure ingress (webhook secret or Telegram/Discord verification)
4. Test in [virtual wallet mode](/guides/sandbox)
5. Submit for review and wait for `beta` approval
6. Gather beta feedback, then request promotion to `public`
## Subscriber eligibility
Only **`beta`** and **`public`** agents process executable signals. `pending-review` returns `agent_status_blocked` skip reasons.
# API keys and HMAC signing
Source: https://docs.echozero.app/guides/api-keys-hmac
Authenticate REST and MCP requests with API keys and required request signing.
## API key authentication
Send your developer API key on every authenticated request using either header:
```bash theme={null}
curl https://mcp.echozero.app/api/v1/users/me \
-H "x-api-key: ez_live_..."
```
```bash theme={null}
curl https://mcp.echozero.app/api/v1/users/me \
-H "Authorization: Bearer ez_live_..."
```
Create and revoke keys in the [Dev Portal](https://devportal.echozero.app). Each key has scoped permissions - request only the scopes your integration needs.
### Common scopes
| Scope | Typical use |
| -------------------------------------- | -------------------------------- |
| `read:agents` / `write:agents` | Agent CRUD, webhook provisioning |
| `read:strategies` / `write:strategies` | Strategy configuration |
| `read:wallet` / `write:wallet` | Balances, virtual mode |
| `read:trades` | Trade and signal history |
| `read:earn` | Earnings and claims |
## Required REST HMAC signing
Every API-key authenticated request must be signed with the **API secret** returned when the key was created. JWT and OAuth bearer session tokens are exempt.
| Header | Description |
| ------------- | ----------------------------------------------------------- |
| `x-api-key` | Your API key id (`ez_live_...`) |
| `x-signature` | `HMAC-SHA256(secretKey, stringToSign)` as lowercase hex |
| `x-timestamp` | Epoch **milliseconds**; rejected if drift exceeds 5 minutes |
### String to sign
```
stringToSign = timestamp + METHOD + path + body
```
* `METHOD` - uppercase HTTP verb (`GET`, `POST`, …)
* `path` - full request path including query string (e.g. `/api/v1/developers/earnings`)
* `body` - raw JSON string for POST/PUT/PATCH, or empty string when there is no body
REST HMAC uses **milliseconds** and includes the HTTP method and path. This is **different** from [inbound agent webhook](/guides/webhook-security) signing, which uses **seconds** and canonical JSON only.
### curl example (GET)
```bash theme={null}
API_KEY="ez_live_..."
SECRET="ezs_..." # secret shown once at key creation
TS=$(date +%s%3N)
REQ_PATH="/api/v1/users/me"
SIG=$(printf '%s' "${TS}GET${REQ_PATH}" | openssl dgst -sha256 -hmac "$SECRET" | awk '{print $2}')
curl -sS "https://mcp.echozero.app${REQ_PATH}" \
-H "x-api-key: $API_KEY" \
-H "x-timestamp: $TS" \
-H "x-signature: $SIG"
```
### curl example (POST)
```bash theme={null}
API_KEY="ez_live_..."
SECRET="ezs_..."
TS=$(date +%s%3N)
REQ_PATH="/api/api-keys"
BODY='{"name":"HMAC Test Key"}'
SIG=$(printf '%s' "${TS}POST${REQ_PATH}${BODY}" | openssl dgst -sha256 -hmac "$SECRET" | awk '{print $2}')
curl -sS -X POST "https://mcp.echozero.app${REQ_PATH}" \
-H "x-api-key: $API_KEY" \
-H "Content-Type: application/json" \
-H "x-timestamp: $TS" \
-H "x-signature: $SIG" \
-d "$BODY"
```
### Python (echozero-sdk)
```python theme={null}
import os
from echozero import EchoZeroClient
client = EchoZeroClient(
api_key=os.environ["EZ_API_KEY"],
hmac_secret_key=os.environ["EZ_SECRET_KEY"],
)
me = client.get("/api/v1/users/me", hmac=True)
print(me)
```
`hmac=True` is the default for API-key clients — every request is signed automatically.
### TypeScript (echozero-sdk)
```typescript theme={null}
import { EchoZeroClient } from '@echozero/sdk';
const client = new EchoZeroClient({
apiKey: process.env.EZ_API_KEY!,
hmacSecretKey: process.env.EZ_SECRET_KEY,
});
const me = await client.get('/api/v1/users/me', { hmac: true });
```
The SDK signs every API-key request by default when `hmacSecretKey` is configured.
Or sign manually with `signRestRequest`:
```typescript theme={null}
import { signRestRequest } from '@echozero/sdk';
const headers = await signRestRequest({
secretKey: process.env.EZ_SECRET_KEY!,
method: 'GET',
path: '/api/v1/users/me',
});
// headers['x-timestamp'], headers['x-signature']
```
## HMAC error responses
| Condition | HTTP | Message |
| ------------------------------------ | ---- | ------------------------------------- |
| Missing `x-signature` (API key auth) | 401 | Missing x-signature header |
| Missing `x-timestamp` | 401 | Missing x-timestamp header |
| Non-numeric timestamp | 401 | Invalid x-timestamp value |
| Timestamp > 5 min drift | 401 | Request timestamp expired |
| Wrong signature | 401 | Invalid HMAC signature |
| Key has no secret | 401 | API key does not support HMAC signing |
## MCP authentication
API keys (with required HMAC) work on `POST https://mcp.echozero.app/mcp` the same way as REST. Send `x-api-key` or `Authorization: Bearer` on every MCP call, including `initialize`. See the [MCP Server guide](/guides/mcp).
# Authentication overview
Source: https://docs.echozero.app/guides/authentication
Which credential to use for REST, webhooks, MCP, OAuth, and outbound callbacks.
EchoZero uses **five credential types**. Pick the one that matches your integration surface.
## Decision table
| I am building… | Credential | Where to get it |
| -------------------------------- | ----------------------------------------------- | -------------------------------------------- |
| Server REST integration | API key (`ez_live_`) + optional secret (`ezs_`) | [Dev Portal](https://devportal.echozero.app) |
| AI assistant / MCP client | OAuth bearer token **or** API key | [OAuth flow](/guides/oauth) or Dev Portal |
| Inbound agent webhook | Per-agent secret (`ezw_`) | Agent create / rotate response |
| Outbound execution callback | Agent `webhookUrl` signing secret | Agent configuration |
| End-user session (rare for devs) | User JWT from `/api/auth/*` | Mobile/web app auth, not typical for bots |
## API key + REST HMAC
```bash theme={null}
curl https://mcp.echozero.app/api/v1/users/me \
-H "x-api-key: ez_live_..."
```
Required HMAC signing for API-key routes. See [API keys + HMAC](/guides/api-keys-hmac).
## OAuth (assistants)
PKCE authorization code flow. Access tokens last **1 hour**. There is **no refresh token** today: re-run the consent flow or use long-lived API keys for headless servers.
## Inbound webhook HMAC
```bash theme={null}
X-EZ-Timestamp:
X-EZ-Signature: HMAC_SHA256(ezw_secret, "${ts}.${canonicalJson}")
```
Different algorithm from REST HMAC. See [Webhook security](/guides/webhook-security).
## Scopes
OAuth and API keys share the same scope strings. Prefer the `read:*` / `write:*` form:
| Scope | Access |
| -------------------------------------- | ------------------------------------------------------------------- |
| `read:agents` / `write:agents` | Agent CRUD |
| `read:strategies` / `write:strategies` | Strategy bots |
| `read:wallet` / `write:wallet` | Wallet and virtual mode |
| `read:trades` | Trade history |
| `trades:execute` | Trade execution (legacy alias; prefer `write:wallet` + agent flows) |
| `read:earn` | Earnings and claims |
| `read:ai` / `write:ai` | AI chat tools |
| `admin:*` | Platform admin only (not available via OAuth) |
Legacy aliases (`agents:read`, `bots:write`, etc.) still work.
## MCP authentication
Send the same API key or OAuth token on **every** MCP request, including `initialize`. Sessions are credential-bound. See [MCP Server](/guides/mcp).
## Protected endpoints
All `/api/v1/*` routes (except public marketplace browse and inbound webhooks) require authentication. The API Reference playground may label auth as optional for try-it convenience; production calls **must** include credentials.
# API conventions
Source: https://docs.echozero.app/guides/conventions
Pagination, response envelopes, idempotency, and rate limits.
## Base URL
```
https://mcp.echozero.app/api
```
Download the OpenAPI spec: [https://mcp.echozero.app/api/docs-json](https://mcp.echozero.app/api/docs-json)
## Response envelope
Success:
```json theme={null}
{ "success": true, "data": { } }
```
Paginated lists:
```json theme={null}
{
"success": true,
"data": { "items": [], "meta": { "page": 1, "limit": 25, "total": 100 } }
}
```
Errors: see [Error codes](/guides/error-codes).
## Pagination
Query parameters on list endpoints:
| Param | Default | Max | Description |
| --------- | ----------- | ----- | ------------------------------- |
| `page` | `1` | - | 1-based page index |
| `limit` | `25` | `100` | Page size |
| `order` | `desc` | - | `asc` or `desc` |
| `orderBy` | `createdAt` | - | Sort field (varies by endpoint) |
Example paging loop:
```bash theme={null}
PAGE=1
while true; do
RESP=$(curl -sS "https://mcp.echozero.app/api/v1/trades?page=$PAGE&limit=100" \
-H "x-api-key: $EZ_API_KEY")
# process RESP.data.items
TOTAL=$(echo "$RESP" | jq '.data.meta.total')
LIMIT=$(echo "$RESP" | jq '.data.meta.limit')
if [ "$((PAGE * LIMIT))" -ge "$TOTAL" ]; then break; fi
PAGE=$((PAGE + 1))
done
```
## Rate limits
| Tier | Limit |
| ---------- | -------------------- |
| `free` | 60 requests / minute |
| `standard` | 300 / minute |
| `premium` | 1000 / minute |
Headers: `X-RateLimit-Limit`, `X-RateLimit-Remaining`, `X-RateLimit-Reset`, `Retry-After` (on 429).
## Idempotency
| Write type | Key |
| --------------------- | ------------------------------------------------------------------------------------------- |
| Inbound signals | `idempotencyKey` on every signal (required for structured; **strongly recommended for NL**) |
| Developer API signals | `idempotencyKey` ≥ 8 chars → stable `sig_api_{agentId}_{key}` |
| MCP destructive tools | Confirmation flow with TTL |
## Authentication required
Unless documented as public (marketplace browse, inbound webhooks, OAuth authorize), all `/api/v1/*` routes require `x-api-key` or `Authorization: Bearer`.
## Versioning
API paths are prefixed with `/v1/`. See [Versioning policy](/guides/versioning).
# Earnings and payouts
Source: https://docs.echozero.app/guides/earnings
Marketplace revenue, subscriber fees, strategy claims, and Stripe Connect payouts.
Developers earn from agent subscriptions, subscriber success fees, and related marketplace revenue splits. Use the developer revenue and claims endpoints to inspect balances, claim earnings, and track payout history.
All routes require developer registration and API key authentication with HMAC signing — see [API keys and HMAC](/guides/api-keys-hmac).
## Fee economics
| Stream | Who pays | Rate | Developer share |
| ---------------- | ------------------------------------------ | ------------------------------------------------------- | -------------------------------------------------------------------------- |
| **Subscription** | Subscriber monthly | You set `monthlyPrice` | **80%** of invoice (platform **20%** via Stripe `application_fee_percent`) |
| **Success fee** | Subscriber on **profitable** closed trades | You set `successFeePercent` (e.g. 10-20% of **profit**) | **80%** of collected success fee (platform **20%**) |
| **Both** | Subscribers | Subscription + success fee | Combined per above |
### Worked example: success fee
A subscriber follows your signal with a **$10,000** buy. The position closes at **+20%** profit (**$2,000** profit USD).
Your agent `successFeePercent` is **15%** (applied to profit on close, not entry notional):
1. Success fee assessed: $2,000 × 15% = **$300\*\*
2. Platform share (20%): **\$60**
3. Your net success fee: **\$240** (claimable via strategy-fee claims)
Success fees accrue on **realized profit** when trades close (`accrueSubscriberFeesOnClose`). Fees are not charged on entry notional unless you configure legacy `feeConfiguration.chargeOnPerformance: false` on non-marketplace bots.
### Worked example: subscription
You set `monthlyPrice: 29`. Ten subscribers pay for one month.
1. Gross: **\$290**
2. Platform fee (20%): **\$58**
3. Creator share via Stripe Connect: **\$232**
## Monetization models
Set on agent create/update (`pricingModel`):
| Model | Fields |
| -------------- | ------------------------------------ |
| `subscription` | `monthlyPrice` + Stripe Connect |
| `success-fee` | `successFeePercent` |
| `both` | `monthlyPrice` + `successFeePercent` |
| `free` | No charge |
Set subscription price via agent subscription endpoints or Dev Portal. Stripe Connect onboarding is required before paid subscriptions route creator share.
## Revenue streams
| Stream | Description | Claim path |
| ------------------------- | --------------------------------------------------------------------- | -------------------------------------------------------------- |
| **Subscriptions** | Monthly agent subscription revenue (creator share via Stripe Connect) | `POST /v1/developers/claim-subscription-earnings` |
| **Strategy success fees** | Per-trade success fees from subscriber executions | `POST /v1/developers/claims/agents/{agentId}` or `/claims/all` |
| **Weekly payouts** | Automated weekly settlement (gross, platform fee, net) | Recorded in payout history - no manual claim |
## Key endpoints
### Earnings summary
```
GET /api/v1/developers/earnings
```
Returns:
* `totals` - lifetime success-fee totals from weekly payouts
* `byAgent` / `byPeriod` - breakdowns
* `fromSubscriptions` - subscription ledger with `claimableUsd`
* `fromTrading.claimableUsd` - claimable strategy success fees
* `totalClaimableUsd` - combined claimable balance
Check this before claiming.
### Payout history
```
GET /api/v1/developers/payouts?page=1&limit=20
```
Paginated weekly payout rows: gross amount, platform fee, net paid.
### Claim subscription earnings
```
POST /api/v1/developers/claim-subscription-earnings
```
Marks all `CLAIMABLE` subscription creator earnings as `CLAIMED`. Returns total USD claimed and number of ledger rows updated.
Returns **400** when there is nothing to claim. Call `GET /earnings` first to check `fromSubscriptions.claimableUsd`.
### Strategy success fee claims
```
GET /api/v1/developers/claims/strategy-fees # per-agent claimable summary
POST /api/v1/developers/claims/agents/{agentId} # claim one agent
POST /api/v1/developers/claims/all # claim all owned agents
```
Per-agent claims drain success-fee balances (SOL transfer), mark subscription-ledger rows `CLAIMED`, and support legacy bot `feeEarnings`. Capped at `CLAIM_MAX_USD` per agent per call.
Returns **404** if the agent is not found or not owned by the caller.
## Stripe Connect
Paid agent subscriptions route creator share (80%) via Stripe Connect `transfer_data`. Complete onboarding before publishing paid agents.
### Start onboarding
```
POST /api/v1/developers/stripe-connect/onboarding
```
Creates a Connect Express account when missing, then returns a hosted onboarding URL. Status updates via Stripe `account.updated` webhooks.
### Check status
```
GET /api/v1/developers/stripe-connect/summary
```
Returns Connect account status, USD balances, next payout estimate, lifetime paid payouts, and subscription MRR / churn metrics.
### Dashboard link
```
POST /api/v1/developers/stripe-connect/dashboard-link
```
Returns a short-lived URL to the Stripe Express dashboard for tax forms and payout settings.
## Typical workflow
Complete developer registration in the [Dev Portal](https://devportal.echozero.app) or via `POST /api/v1/developers/register`.
Call `POST /stripe-connect/onboarding` and complete the hosted flow before enabling paid subscriptions.
Create marketplace agents with subscription pricing. Subscriber payments flow through Connect.
Poll `GET /v1/developers/earnings` for claimable balances and `GET /payouts` for settlement history.
* Subscription ledger: `POST /claim-subscription-earnings`
* Strategy success fees: `POST /claims/agents/{agentId}` or `POST /claims/all`
## Dashboard analytics
Additional developer dashboard routes (subscribers, performance, signal history) are under the **Developer dashboard** tag in the API Reference. These complement earnings data for operational monitoring.

# Error codes
Source: https://docs.echozero.app/guides/error-codes
Common API error shapes, HTTP status codes, MCP JSON-RPC errors, and retry guidance.
EchoZero REST responses use a consistent envelope. MCP protocol errors use JSON-RPC 2.0 format on `/mcp` routes.
## REST response envelope
### Success
```json theme={null}
{
"success": true,
"data": { }
}
```
Paginated endpoints wrap items in `data` with `meta` (page, limit, total).
### Error
```json theme={null}
{
"success": false,
"error": {
"code": "UNAUTHORIZED",
"message": "Missing or invalid API key"
}
}
```
The `code` field is derived from the HTTP status:
| HTTP | `error.code` |
| ---- | ----------------------- |
| 400 | `BAD_REQUEST` |
| 401 | `UNAUTHORIZED` |
| 403 | `FORBIDDEN` |
| 404 | `NOT_FOUND` |
| 409 | `CONFLICT` |
| 429 | `TOO_MANY_REQUESTS` |
| 5xx | `INTERNAL_SERVER_ERROR` |
Validation errors on **400** may include a comma-joined message from field validators.
## Common HTTP statuses
| Status | Meaning | Retry? |
| ------ | ------------------------------------------------------------------------------------ | ----------------------------------------- |
| `400` | Validation error, malformed JSON, or business rule violation (e.g. nothing to claim) | Fix request - do not retry blindly |
| `401` | Missing/invalid API key, OAuth token, or HMAC signature | Refresh credentials |
| `403` | Authenticated but insufficient scope, or MCP session bound to different credential | Check scopes or re-initialize MCP session |
| `404` | Resource not found, or developer not registered | Verify ids and registration |
| `409` | Conflict (duplicate resource) | Use idempotency key or fetch existing |
| `429` | Rate limit exceeded | Retry after `Retry-After` seconds |
| `5xx` | Server error | Retry with exponential backoff |
## Authentication errors
| Message | Cause |
| ----------------------------------------------------- | ----------------------------------------------------- |
| `Missing x-timestamp header` | `x-signature` sent without `x-timestamp` |
| `Invalid x-timestamp value` | Non-numeric timestamp |
| `Request timestamp expired (drift exceeds 5 minutes)` | Clock skew on REST HMAC |
| `Invalid HMAC signature` | Wrong secret, path, method, or body in string-to-sign |
| `API key does not support HMAC signing` | Key created without a secret |
Inbound agent webhook errors return the same envelope with **401** for invalid `X-EZ-Signature` or clock skew.
## Rate limits
Authenticated requests include rate limit headers:
| Header | Description |
| ----------------------- | --------------------------------- |
| `X-RateLimit-Limit` | Max requests per 60-second window |
| `X-RateLimit-Remaining` | Requests left in current window |
| `X-RateLimit-Reset` | Unix epoch when the window resets |
| `Retry-After` | Seconds to wait (only on 429) |
### Tiers
| Tier | Limit |
| ---------- | ------------ |
| `free` | 60 req/min |
| `standard` | 300 req/min |
| `premium` | 1000 req/min |
Rate limits apply per API key or OAuth user id.
## MCP JSON-RPC errors
MCP routes (`POST /mcp`, `GET /mcp/sse`) return JSON-RPC errors instead of the REST envelope:
```json theme={null}
{
"jsonrpc": "2.0",
"error": {
"code": -32001,
"message": "Missing or invalid API key"
},
"id": null
}
```
| JSON-RPC code | HTTP | Meaning |
| ------------- | --------- | -------------------------------------------- |
| `-32001` | 401 | Unauthorized |
| `-32002` | 403 | Forbidden (e.g. session/credential mismatch) |
| `-32003` | 429 | Rate limit exceeded |
| `-32602` | 400 | Invalid params |
| `-32603` | 5xx | Internal error |
| `-32000` | other 4xx | Application error |
### MCP session errors
| Scenario | Code | Fix |
| -------------------------------------------- | ------ | -------------------------------------------- |
| Missing `mcp-session-id` after initialize | 400 | Send session header from initialize response |
| Session created with different API key/token | -32002 | Re-run `initialize` with the same credential |
| Expired or unknown session | 401 | Re-run `initialize` |
## Signal ingestion outcomes
Inbound signal webhooks return **200** with an `outcome` field even when no trade executes:
| `outcome` | Meaning |
| ----------- | ---------------------------------------------------------- |
| `matched` | Signal parsed and accepted for processing |
| `unmatched` | Parser could not match the message |
| `skipped` | Intentionally skipped (e.g. non-entry action, eligibility) |
| `error` | Processing error - check `skipReason` |
Treat `skipped` and `unmatched` as non-retryable unless you change the payload.
## Signal validation errors (HTTP 400)
| Error | Cause | Fix |
| ----------------------- | ---------------------------------------- | ------------------------------------------- |
| Missing `reasoning` | Structured `eventType` without rationale | Add 1-4000 char `reasoning` |
| Invalid `eventType` | Unknown enum value | Use documented event types |
| Missing `positionRef` | Lifecycle event without reference | Set to entry `idempotencyKey` or `signalId` |
| Stale `clientTimestamp` | Market signal older than 5 min | Use current ISO timestamp |
| Invalid `instrument` | Missing token/market for chain | Provide `instrument.tokenAddress` or `coin` |
## `skipReason` dictionary (selected)
| `skipReason` | Retryable? | Meaning |
| -------------------------------------- | ---------- | --------------------------------- |
| `parser_unmatched` | No | NL text did not match grammar |
| `agent_status_blocked` | No | Agent not `beta`/`public` |
| `agent_paused` | No | Agent paused |
| `token_unresolved` | No | Could not map ticker |
| `token_not_supported` | No | Token not on execution venue |
| `token_blocked_by_whitelist` | No | Token not on agent whitelist |
| `non_entry_action` | No | Sell/cancel without open position |
| `duplicate_request` | No | Idempotency key reused (safe) |
| `lifecycle_update_no_open_trade_found` | No | `positionRef` not found |
## Execution error tags (in `executionResult.errorMessage`)
| Code | Retryable? | Meaning |
| ------------------------------------------- | ---------- | ------------------------------------- |
| `wallet_not_found` | No | Subscriber wallet missing |
| `subscription_paused` | No | Subscription inactive |
| `signal_no_amount_set` | No | No USD size configured |
| `BUY_FAILED` | Maybe | On-chain/venue failure; check details |
| `hyperliquid_not_available_in_virtual_mode` | No | Use live mode for perps |
| `sell_not_available_in_virtual_mode` | No | Virtual mode limitation |
Full registry: see `ingestReasons.ts` in the backend.
## Retry guidance
| Error type | Strategy |
| --------------- | ----------------------------------------------------------------- |
| 429 | Wait `Retry-After`, then retry |
| 5xx | Exponential backoff (1s, 2s, 4s, …) with jitter, max 3-5 attempts |
| Network timeout | Retry with same `idempotencyKey` for signal POSTs |
| 401 HMAC | Fix signing - do not retry without correction |
| 400 validation | Fix payload - retries will fail identically |
## Debugging tips
* Compare your string-to-sign against the SDK's `signRestRequest` output for REST HMAC.
* For inbound webhooks, verify canonical JSON key ordering matches `stableJson` in echozero-sdk.
* Check `X-RateLimit-Remaining` before bulk operations.
* Use `GET /status` to verify OAuth tokens without hitting scoped routes.
# MCP Server
Source: https://docs.echozero.app/guides/mcp
Connect AI assistants to EchoZero via Model Context Protocol (Streamable HTTP).
EchoZero exposes an [MCP](https://modelcontextprotocol.io/) server so Claude, ChatGPT, Cursor, and other assistants can call tools, read resources, and use prompts on behalf of authenticated users.
`https://mcp.echozero.app/mcp` is a **JSON-RPC POST endpoint**, not a web page. Opening it in a browser (GET) returns an error. Configure your MCP client to send `POST` requests instead.
## Endpoints
| Surface | URL | Method |
| --------------------- | -------------------------------------------- | -------------------------- |
| MCP (Streamable HTTP) | `https://mcp.echozero.app/mcp` | `POST` |
| MCP SSE stream | `https://mcp.echozero.app/mcp/sse` | `GET` (after `initialize`) |
| End session | `https://mcp.echozero.app/mcp` | `DELETE` |
| Directory metadata | `https://mcp.echozero.app/public/index.json` | `GET` |
## Authentication
Send credentials on **every** MCP request, including the first `initialize`:
* `x-api-key: `, or
* `Authorization: Bearer ` (API key or [OAuth token](/guides/oauth))
REST HMAC headers (`x-signature`, `x-timestamp`) are **required** for API-key auth. See [API keys + HMAC](/guides/api-keys-hmac). JWT/OAuth session tokens are exempt.
## Session lifecycle
`POST /mcp` with `method: "initialize"`. Save the `mcp-session-id` response header.
`POST /mcp` with `method: "notifications/initialized"` and the session header.
Include `mcp-session-id: ` on all subsequent requests.
`GET /mcp/sse` with `Accept: text/event-stream` and the session header for server-push events.
`DELETE /mcp` with the session header when done.
Sessions are **bound to the credential** used at `initialize`. Using a different API key or OAuth token with the same `mcp-session-id` returns **403** (JSON-RPC `-32002`).
Response headers may also include `X-Mcp-Instance-Id` for load-balancer sticky routing in multi-instance deployments.
## Example `initialize` request
```bash theme={null}
curl -sS https://mcp.echozero.app/mcp \
-H "x-api-key: $EZ_API_KEY" \
-H "Content-Type: application/json" \
-H "Accept: application/json, text/event-stream" \
-d '{
"jsonrpc": "2.0",
"id": 1,
"method": "initialize",
"params": {
"protocolVersion": "2025-03-26",
"capabilities": {},
"clientInfo": { "name": "my-client", "version": "1.0.0" }
}
}'
```
Save `mcp-session-id` from the response headers.
## Example `tools/list`
```bash theme={null}
curl -sS https://mcp.echozero.app/mcp \
-H "x-api-key: $EZ_API_KEY" \
-H "Content-Type: application/json" \
-H "Accept: application/json, text/event-stream" \
-H "mcp-session-id: $MCP_SESSION_ID" \
-d '{
"jsonrpc": "2.0",
"id": 2,
"method": "tools/list"
}'
```
## Tools, resources, and scopes
Available MCP tools, resources, and prompts are **scope-gated** by the API key or OAuth token. Common scopes:
| Scope | Capability |
| -------------------------------------- | ------------------------ |
| `read:agents` / `write:agents` | Agent management tools |
| `read:wallet` / `write:wallet` | Wallet and balance tools |
| `read:strategies` / `write:strategies` | Strategy configuration |
| `read:trades` | Trade and signal history |
| `read:tokens` | Token metadata |
| `write:ai` | AI chat tools |
Tools forward to the same REST endpoints documented in the API Reference. Errors use JSON-RPC format - see [Error codes](/guides/error-codes).
See the full [Tools Reference](/mcp/tools) and [Resources](/mcp/resources) for the out-of-band catalog (no runtime `tools/list` required).
## OAuth for assistant directories
For ChatGPT, Claude, Gemini, and other directory submissions:
| Setting | Value |
| ------------- | ---------------------------------------------- |
| MCP URL | `https://mcp.echozero.app/mcp` |
| Authorize URL | `https://mcp.echozero.app/oauth/authorize` |
| Token URL | `https://mcp.echozero.app/oauth/token` |
| Scopes | From `/public/directory/{platform}/` manifests |
Fetch connector metadata:
```
https://mcp.echozero.app/public/index.json
```
See the [OAuth guide](/guides/oauth) for the full PKCE flow.
## Assistant setup (coming soon)
**Coming soon:** `npx skills add EchoZeroApp/skills` and `ez login` are not yet public. Use API keys or [OAuth](/guides/oauth) today.
```bash theme={null}
# When available:
npx skills add EchoZeroApp/skills
ez login
```
# OAuth 2.1
Source: https://docs.echozero.app/guides/oauth
Authorization code + PKCE for AI assistant and CLI clients.
EchoZero supports OAuth 2.1 authorization code with PKCE for clients that cannot safely store long-lived API keys - Claude connectors, ChatGPT apps, local CLIs, and directory integrations.
## Endpoints
| Step | Method | URL |
| -------------------- | ------ | -------------------------------------------------- |
| Client lookup | `GET` | `https://mcp.echozero.app/oauth/client` |
| Authorize | `GET` | `https://mcp.echozero.app/oauth/authorize` |
| Approve (Dev Portal) | `POST` | `https://mcp.echozero.app/oauth/authorize/approve` |
| Token | `POST` | `https://mcp.echozero.app/oauth/token` |
| Introspect | `POST` | `https://mcp.echozero.app/oauth/introspect` |
| Verify status | `GET` | `https://mcp.echozero.app/status` |
User consent is handled in the Dev Portal at [devportal.echozero.app/mcp/oauth/authorize](https://devportal.echozero.app/mcp/oauth/authorize). Users approve from their saved portal session - do not ask them to copy JWTs from browser devtools.
## PKCE parameters
| Parameter | Required | Value |
| ----------------------- | -------- | -------------------------------------------- |
| `response_type` | Yes | `code` |
| `client_id` | Yes | Registered client id (e.g. `echozero-cli`) |
| `redirect_uri` | Yes | Must match a registered redirect URI exactly |
| `scope` | Yes | Space-delimited OAuth scopes (see below) |
| `state` | Yes | Opaque CSRF token - validate on callback |
| `code_challenge` | Yes | `BASE64URL(SHA256(code_verifier))` |
| `code_challenge_method` | Yes | `S256` |
Generate a `code_verifier` (43-128 random characters) and keep it secret until token exchange.
## Browser consent flow
Send the user to `GET https://mcp.echozero.app/oauth/authorize` with PKCE `code_challenge`, `state`, `scope`, and `redirect_uri`.
```bash theme={null}
# Example authorize URL (build in your app)
https://mcp.echozero.app/oauth/authorize\
?response_type=code\
&client_id=echozero-cli\
&redirect_uri=http://127.0.0.1:8765/callback\
&scope=read:agents%20read:wallet\
&state=random-csrf-token\
&code_challenge=E9Melhoa2OwvFrEMTJguCHaoeK1t8URWbuGJSstw-cM\
&code_challenge_method=S256
```
EchoZero redirects to the Dev Portal consent page. If the user is not signed in, they authenticate first, then approve the requested scopes.
EchoZero redirects back to your `redirect_uri` with `?code=...&state=...`. Verify `state` matches what you sent.
```bash theme={null}
curl -sS -X POST https://mcp.echozero.app/oauth/token \
-H "Content-Type: application/json" \
-d '{
"grant_type": "authorization_code",
"code": "",
"redirect_uri": "http://127.0.0.1:8765/callback",
"client_id": "echozero-cli",
"code_verifier": ""
}'
```
Response:
```json theme={null}
{
"access_token": "ez_oauth_...",
"token_type": "Bearer",
"expires_in": 3600,
"scope": "read:agents read:wallet"
}
```
Send `Authorization: Bearer ` on REST and MCP requests.
## Verify the token
After login, confirm the token is active:
```bash theme={null}
curl -sS https://mcp.echozero.app/status \
-H "Authorization: Bearer $OAUTH_TOKEN"
```
For server-side validation without calling user-scoped routes:
```bash theme={null}
curl -sS -X POST https://mcp.echozero.app/oauth/introspect \
-H "Content-Type: application/json" \
-d '{ "token": "'"$OAUTH_TOKEN"'" }'
```
Returns `{ "active": true, "sub": "...", "client_id": "...", "scope": "...", "exp": ... }` when valid.
## OAuth scopes
Scopes map to API key permissions. Request only what your integration needs:
| Scope | Access |
| -------------------------------------------- | -------------------------------- |
| `read:agents` / `write:agents` | List and manage developer agents |
| `read:strategies` / `write:strategies` | Strategy configuration |
| `read:wallet` / `write:wallet` | Wallet balances and mode |
| `read:trades` / `trades:execute` | Trade history and execution |
| `read:tokens` | Token metadata |
| `read:earn` | Earnings and claims |
| `read:analytics` | Dashboard analytics |
| `read:ai` / `write:ai` | AI chat and tooling |
| `read:notifications` / `write:notifications` | Notification preferences |
Legacy scope aliases (`agents:read`, `bots:write`, etc.) are also accepted. `admin:*` is not available via OAuth.
## Token lifetime and refresh
| Token | TTL | Notes |
| ------------------ | ------------------------------- | ---------------------------------- |
| Authorization code | **5 minutes** | Single use; exchanged immediately |
| Access token | **1 hour** (`expires_in: 3600`) | No `refresh_token` is issued today |
When the access token expires, **re-run the PKCE consent flow** or use a long-lived **API key** for headless servers. There is no `offline_access` or refresh grant at this time.
### `code_verifier` requirements
43-128 characters from `[A-Z]`, `[a-z]`, `[0-9]`, `.`, `-`, `_`, `~` (unreserved URI characters).
## OAuth error responses
| Condition | HTTP | Message / behavior |
| --------------------------- | ---- | --------------------------------------- |
| Expired or reused code | 400 | `Invalid or expired authorization code` |
| PKCE mismatch | 400 | `Invalid code_verifier` |
| Wrong `redirect_uri` | 400 | Redirect URI mismatch |
| Invalid `client_id` | 400 | Unknown client |
| Invalid `state` on callback | — | Your app should reject the callback |
## MCP with OAuth
OAuth tokens work on MCP the same way as API keys:
1. `POST https://mcp.echozero.app/mcp` with `Authorization: Bearer ` on **every** request, including `initialize`.
2. Save the `mcp-session-id` response header from `initialize`.
3. Send `mcp-session-id: ` on subsequent MCP calls (`tools/list`, `tools/call`, SSE stream, etc.).
MCP sessions are **bound to the credential** used at `initialize`. Switching API keys or OAuth tokens while reusing the same `mcp-session-id` returns **403** with JSON-RPC error code `-32002`.
See the [MCP Server guide](/guides/mcp) for a full `initialize` example.
## Assistant setup (coming soon)
**Coming soon:** The public skills pack (`EchoZeroApp/skills`) and `ez login` CLI are not yet published. Use the PKCE flow above or API keys until the skills repo is public.
```bash theme={null}
# When available:
npx skills add EchoZeroApp/skills
ez login
```
## Directory integrations
For ChatGPT, Claude, Gemini, and other assistant directories, use connector metadata from:
```
https://mcp.echozero.app/public/index.json
```
Per-platform manifests live under `/public/directory/*` with authorize URL, token URL, and recommended scope lists.
# Sandbox testing
Source: https://docs.echozero.app/guides/sandbox
Test integrations against the public EchoZero API without affecting live subscribers or executing real trades.
External developers test against the **production API host** - there is no separate public staging environment and you do not need access to EchoZero source code.
**Base URL:** `https://mcp.echozero.app/api`
## 1. Create a developer account and API key
1. Sign in at [devportal.echozero.app](https://devportal.echozero.app).
2. Register as a developer and create an API key.
3. Export it locally:
```bash theme={null}
export EZ_API_KEY="ez_live_..."
```
All examples below send this key as `x-api-key`.
## 2. Dry-run sandbox endpoints
The **Sandbox** API group provides dry-run simulators - they validate ownership and return simulated results with **no real execution**.
### Simulate a trade for your agent
```bash theme={null}
curl -sS -X POST "https://mcp.echozero.app/api/sandbox/agents/{agentId}/trade" \
-H "x-api-key: $EZ_API_KEY" \
-H "Content-Type: application/json" \
-d '{
"pair": "SOL/USDC",
"amount": 100,
"action": "BUY"
}'
```
### Simulate signal parsing for an agent
```bash theme={null}
curl -sS -X POST "https://mcp.echozero.app/api/sandbox/agents/{agentId}/signals/simulate" \
-H "x-api-key: $EZ_API_KEY" \
-H "Content-Type: application/json" \
-d '{
"message": "Buy SOL at $145, TP $160, SL $138"
}'
```
### List sandbox signal history
```bash theme={null}
curl -sS "https://mcp.echozero.app/api/sandbox/agents/{agentId}/signals?page=1&limit=20" \
-H "x-api-key: $EZ_API_KEY"
```
See the **Sandbox** tag in the API Reference sidebar for full request/response schemas.
## 3. Virtual wallet (paper trading)
Switch to virtual wallet mode and add simulated funds before testing buy/sell flows:
```bash theme={null}
# Toggle to virtual mode
curl -sS -X POST "https://mcp.echozero.app/api/v1/wallet/mode" \
-H "x-api-key: $EZ_API_KEY" \
-H "Content-Type: application/json" \
-d '{ "isVirtualMode": true }'
# Add virtual SOL balance
curl -sS -X POST "https://mcp.echozero.app/api/v1/wallet/virtual/add-funds" \
-H "x-api-key: $EZ_API_KEY" \
-H "Content-Type: application/json" \
-d '{ "amountInSol": 10 }'
```
Virtual trades use simulated balances - no on-chain execution.
## 4. Portal demo signals
To record a demo signal row for an agent (isolated from live subscriber execution), use:
```bash theme={null}
curl -sS -X POST "https://mcp.echozero.app/api/dev/trade-signals" \
-H "x-api-key: $EZ_API_KEY" \
-H "Content-Type: application/json" \
-d '{
"developerAgentId": "{agentId}",
"action": "buy",
"tokenAddress": "So11111111111111111111111111111111111111112",
"amount": 100
}'
```
Demo signals appear in developer signal history but do not trigger the live trade bridge.
## 5. Test inbound webhook signing
Create a webhook agent in the Dev Portal (`signalSourceKind: webhook`). Save the `inboundWebhookSigningSecretReveal` (`ezw_...`) shown once at creation.
Post a signed test signal:
```bash theme={null}
AGENT_ID="{agentId}"
SECRET="ezw_..."
TS=$(date +%s)
CANON='{"text":"BUY SOL $100"}'
SIG=$(printf '%s' "$TS.$CANON" | openssl dgst -sha256 -hmac "$SECRET" | awk '{print $2}')
curl -sS -X POST "https://mcp.echozero.app/api/public/agent-signals/$AGENT_ID" \
-H "Content-Type: application/json" \
-H "X-EZ-Timestamp: $TS" \
-H "X-EZ-Signature: $SIG" \
-d '{"text":"BUY SOL $100"}'
```
Use [virtual wallet mode](#3-virtual-wallet-paper-trading) so execution uses simulated balances. Full signing details are in [Webhook security](/guides/webhook-security).
## 6. Dev Portal UI
Many flows (agent setup, signal preview, subscriber analytics) can also be exercised from the [Dev Portal](https://devportal.echozero.app) before you wire up production bots.
Use a dedicated test agent with no real subscribers while iterating. When you are ready for live execution, switch to production webhook or structured signal ingestion paths documented in the [Signal envelope](/guides/signal-envelope) and [Webhook security](/guides/webhook-security) guides.
# SDK client libraries
Source: https://docs.echozero.app/guides/sdk
Official TypeScript, Python, Go, and Rust packages for REST, WebSocket, and webhook signing.
**Coming soon:** Packages are not yet published to npm, PyPI, or crates.io. This page documents the finished SDK spec. Use the REST API and [signature test vectors](/guides/signature-test-vectors) until packages ship.
The [echozero-sdk](https://github.com/EchoZeroApp/echozero-sdk) repo provides clients in **four languages**: TypeScript, Python, Go, and Rust.
## Install (when published)
```bash theme={null}
npm install @echozero/sdk
```
```bash theme={null}
pip install echozero
```
```bash theme={null}
go get github.com/EchoZeroApp/echozero-sdk/packages/go/echozero
```
```toml theme={null}
# Cargo.toml
echozero = { git = "https://github.com/EchoZeroApp/echozero-sdk", package = "echozero" }
```
## REST client
```typescript theme={null}
import { EchoZeroClient } from '@echozero/sdk';
const client = new EchoZeroClient({
apiKey: process.env.EZ_API_KEY!,
hmacSecretKey: process.env.EZ_SECRET_KEY,
});
const me = await client.get('/api/v1/users/me', { hmac: true });
```
```python theme={null}
from echozero import EchoZeroClient
client = EchoZeroClient(api_key="ez_live_...", hmac_secret_key="ezs_...")
me = client.get("/api/v1/users/me", hmac=True)
```
## Inbound webhook signing
```typescript theme={null}
import { signInboundWebhook } from '@echozero/sdk';
const headers = await signInboundWebhook({
signingSecret: process.env.EZW_SECRET!,
body: { text: 'BUY SOL $100', idempotencyKey: 'key-1' },
});
```
## WebSocket signal client
Connect to `wss://mcp.echozero.app/ws/signals` with `x-api-key` in the Socket.IO handshake. Emit `signal` events with the same JSON schema as the inbound webhook.
## Verify outbound webhooks
SDK helpers implement `verifyInboundWebhook` and outbound `signal.execution` verification. Golden vectors are in [Signature test vectors](/guides/signature-test-vectors).
# Signal envelope
Source: https://docs.echozero.app/guides/signal-envelope
Structured trade signal events, idempotency keys, and delivery semantics.
Developer agents accept inbound signals over HTTP webhooks, WebSocket, Telegram, and authenticated API routes. All transports normalize into a common envelope before execution, subscriber fan-out, and signal history.
## Inbound endpoint
For webhook-based agents (`signalSourceKind: webhook`):
```
POST https://mcp.echozero.app/api/public/agent-signals/{agentId}
```
Authentication is **per-agent HMAC** (not your developer API key). See [Webhook security](/guides/webhook-security) for signing details.
**Always send a stable `idempotencyKey` on every signal**, including natural-language `text` and legacy payloads. Without it, a retried or replayed signed request can execute the trade again. Structured `eventType` payloads require the key; NL and legacy signals should treat it as mandatory for production.
## Payload modes
Three modes are supported. They are **mutually exclusive** - send one style per request.
| Mode | Trigger | Use when |
| ------------------- | ---------------------------------------------------- | ----------------------------------------------------------------- |
| Natural language | `text` field present | Quick signals parsed like Telegram (`BUY SOL $500 TP 180 SL 165`) |
| Full schema (#1098) | `eventType` present | Lifecycle trades, perps, SL/TP ladders, feed events |
| Legacy structured | `action` + `tokenAddress` (no `text` or `eventType`) | Minimal buy/sell backward compatibility |
## Event types

"reasoning": "Trade running +8.4% unrealized; holding for TP2."
}
```
### Feed-only - trade review
```json theme={null}
{
"eventType": "trade_review",
"idempotencyKey": "review-2026-07-07-008",
"relatedTradeId": "sig_abc123",
"pnlPct": 14.2,
"exitReason": "tp_hit",
"reasoning": "Closed full position at TP2. Clean breakout follow-through."
}
```
### Legacy structured
```json theme={null}
{
"action": "buy",
"tokenAddress": "So11111111111111111111111111111111111111112",
"amount": 500,
"urgency": "medium",
"idempotencyKey": "legacy-001"
}
```
## Idempotency
* **Full schema:** `idempotencyKey` is required when `eventType` is set.
* **Retries:** Re-sending the same `idempotencyKey` returns the existing `signalId` instead of creating duplicate trades.
* **Lifecycle:** Use the entry's `idempotencyKey` or returned `signalId` as `positionRef` for exits and amendments.
Recommended pattern: prefix keys with your system id and date, e.g. `my-bot-2026-07-06-entry-001`.
## Response
Standard MCP envelope. Typical `data` fields:
| Field | Description |
| ------------ | ------------------------------------------------ |
| `outcome` | `matched`, `unmatched`, `skipped`, or `error` |
| `signalId` | Trade signal id when created or reused |
| `status` | Bridge execution status when applicable |
| `skipReason` | Why a signal was skipped (e.g. parser unmatched) |
| HTTP | Cause |
| ---- | ----------------------------------------------------------------- |
| 401 | Invalid HMAC signature or clock skew |
| 404 | Unknown agent or agent not eligible for webhook ingress |
| 400 | Validation error (missing `reasoning`, invalid `eventType`, etc.) |
## Signing secret lifecycle
* **Provision:** Creating an agent with `signalSourceKind: webhook` returns `inboundWebhookSigningSecretReveal` **once** (`ezw_...`).
* **Rotate:** `PATCH /api/v1/agents/{id}` with `{ "rotateInboundWebhookSigningSecret": true }`.
* **Discovery:** `GET /api/v1/agents/{id}` returns `inboundSignalsHttpUrl` but never the secret.
## Other transports
| Transport | Auth | Notes |
| ----------------------------- | ------------------------ | ------------------------------------ |
| Inbound HTTP webhook | Per-agent HMAC | This guide |
| WebSocket `/ws/signals` | Developer API key | Same #1098 schema |
| `POST /api/dev/trade-signals` | Developer API key | Portal sandbox only - no live bridge |
| Telegram / Discord | Provider webhook secrets | Platform-managed parsing |
## Outbound execution callbacks
When you set `webhookUrl` on an agent, EchoZero POSTs `signal.execution` events to your server after trade attempts. This is separate from inbound signing - see [Webhook security](/guides/webhook-security).
# Natural-language signal grammar
Source: https://docs.echozero.app/guides/signal-grammar
Phrases and keywords the EchoZero parser recognizes in text signals.
Natural-language signals (`{ "text": "..." }`) are parsed by the same engine used for Telegram and Discord signal groups. Use this reference when authoring text lines or testing in the [sandbox](/guides/sandbox).
## Entry patterns
| Intent | Example phrases |
| ----------- | ------------------------------------------------- |
| Buy / long | `BUY SOL`, `LONG $BTC`, `APE WIF`, `entry on SOL` |
| Sell / exit | `SELL SOL`, `CLOSE`, `EXIT ALL`, `closed fully` |
| Size | `$500`, `100 USDC`, `500 USD` notional |
| Take profit | `TP 180`, `TP1: 95.00`, `target 2.10` |
| Stop loss | `SL 165`, `stop 0.00372` |
| Leverage | `LEV 5X`, `5x leverage`, `isolated 10x` |
| Entry zone | `ZONE 140-145`, `BETWEEN 0.21 and 0.22` |
| Breakout | `BREAKOUT ABOVE 150`, `BREAK BELOW 140` |
## Lifecycle patterns
| Intent | Keywords |
| ------------- | -------------------------------------------------------- |
| Cancel | `CANCEL`, `INVALIDATED`, `ABORT`, `SETUP BROKEN`, `SKIP` |
| Breakeven | `BREAKEVEN`, `BE`, `MOVE SL TO BE`, `SL TO BE` |
| Partial close | `TAKE HALF`, `CLOSE 50%`, `TRIM`, `SCALE OUT`, `PARTIAL` |
| SL hit | `SL HIT`, `STOPPED OUT`, `HIT SL` |
| Amend SL/TP | `SL updated 165 → 170`, `TP1 retargeted 180` |
## Token resolution
* Tickers: `$SOL`, `SOL`, `WIF` (after entry verbs)
* Contract: Solana mint address in structured/legacy payloads
* Unresolved tickers return `token_unresolved` skip reason
## Multi TP ladders
```
BUY SOL $500 TP1 180 TP2 195 SL 165
TP3: 92.00 - sell 20%
```
## Custom keywords
Per-agent `signalDetectionRule` can override buy/sell/TP/SL keyword lists. Test parsing:
```bash theme={null}
curl -sS -X POST "https://mcp.echozero.app/api/sandbox/agents/{agentId}/signals/simulate" \
-H "x-api-key: $EZ_API_KEY" \
-H "Content-Type: application/json" \
-d '{ "message": "BUY SOL at $145, TP $160, SL $138" }'
```
## Always include idempotency
Always send a stable `idempotencyKey` with NL text signals. Without it, a retried or replayed signed request can execute twice ([bug #391](https://github.com/EchoZeroApp)).
```json theme={null}
{ "text": "BUY SOL $100", "idempotencyKey": "my-bot-2026-07-07-001" }
```
## Structured alternative
For production bots, prefer structured `eventType` payloads in [Signal envelope](/guides/signal-envelope) to avoid parser ambiguity.
# Signal groups (Telegram & Discord)
Source: https://docs.echozero.app/guides/signal-groups
Connect Telegram channels or Discord servers to ingest natural-language signals.
Signal-group agents (`signalSourceKind: signal_group`) are for **Telegram channel** and **Discord server** operators who want EchoZero to parse messages and fan out trades to subscribers.
## Who this is for
* Telegram paid signal groups
* Discord alpha communities
* Operators who post natural-language lines like `BUY SOL $500 TP 180 SL 165`
## Setup flow
```bash theme={null}
curl -sS -X POST https://mcp.echozero.app/api/v1/agents \
-H "x-api-key: $EZ_API_KEY" \
-H "Content-Type: application/json" \
-d '{
"name": "My TG Signals",
"signalSourceKind": "signal_group"
}'
```
```bash theme={null}
curl -sS https://mcp.echozero.app/api/v1/agents/telegram/bot-metadata \
-H "x-api-key: $EZ_API_KEY"
```
Add the EchoZero bot to your Telegram channel as admin. For Discord:
```bash theme={null}
curl -sS https://mcp.echozero.app/api/v1/agents/discord/bot-metadata \
-H "x-api-key: $EZ_API_KEY"
```
**Telegram:** `POST /api/v1/agents/{id}/telegram/verify` with your channel `@username`.
**Discord:** `GET /api/v1/agents/{id}/discord/oauth-url` → complete OAuth → `POST /api/v1/agents/{id}/discord/verify`.
Set `signalDetectionRule` and optional `signalExecutionDefaults` on the agent via `PATCH /api/v1/agents/{id}`. See [Signal grammar](/guides/signal-grammar).
`GET /api/v1/developers/agents/{id}/signals/ingest-log` shows parsed lines, match outcomes, and skip reasons.
## Natural-language parsing
Messages in connected channels run through the deterministic parser documented in [Signal grammar](/guides/signal-grammar). Matched lines enter the same execution bridge as webhook signals.
## Membership gating
Agents can require subscribers to prove Telegram/Discord membership (`membershipGated`). Execution skips subscribers who fail the channel check.
## vs webhook ingress
| | Signal group | Webhook |
| -------- | -------------------------- | ------------------------ |
| Auth | Platform bots | Per-agent `ezw_` HMAC |
| Payload | NL text in channel | HTTP JSON |
| Best for | Existing TG/DC communities | Custom bots, TradingView |

# Signature test vectors
Source: https://docs.echozero.app/guides/signature-test-vectors
Frozen known-answer examples for REST, inbound, and outbound HMAC signing.
Use these vectors to verify your signer matches EchoZero and the official SDK.
**Inbound vs outbound:** Inbound agent signals sign **canonical JSON** (sorted keys, known field set). Outbound `signal.execution` webhooks sign the **raw request body** string. REST HMAC signs `timestamp + METHOD + path + body`.
## REST HMAC (POST)
| Field | Value |
| ---------------------- | ------------------------------------------------------------------ |
| Secret | `test_secret` |
| Timestamp (ms) | `1710000000000` |
| Method | `POST` |
| Path | `/api/api-keys` |
| Body | `{"name":"SDK HMAC Test"}` |
| String to sign | `1710000000000POST/api/api-keys{"name":"SDK HMAC Test"}` |
| Expected `x-signature` | `274c9ff280eadf751530e9e7fce2c2a573d8676b13b7108fe353407df7cc9e00` |
## Inbound webhook (text + idempotencyKey)
| Field | Value |
| ------------------------- | ---------------------------------------------------------------------- |
| Secret | `test_secret` |
| Timestamp (s) | `1710000000` |
| Body | `{"idempotencyKey":"sdk-test-1","text":"BUY SOL 500 USDC"}` |
| Canonical JSON | `{"idempotencyKey":"sdk-test-1","text":"BUY SOL 500 USDC"}` |
| Payload | `1710000000.{"idempotencyKey":"sdk-test-1","text":"BUY SOL 500 USDC"}` |
| Expected `X-EZ-Signature` | `1d30d896fc609e62bcf9be991c1dc1177a9c63219909869ef2846bad4685de3b` |
## Inbound webhook (structured buy, unknown fields stripped)
| Field | Value |
| ------------------------- | -------------------------------------------------------------------- |
| Secret | `secret` |
| Timestamp (s) | `1710000000` |
| Body fields | `eventType`, `idempotencyKey`, `reasoning`, `tokenAddress`, `amount` |
| Extra fields | Ignored for signing (e.g. `unknownField`) |
| Expected `X-EZ-Signature` | `be420f61d91e6b871481774c62f972f0aafa6f5f1a727ba1e4a32558784f77c3` |
Canonical JSON for that vector:
```json theme={null}
{"amount":500,"eventType":"buy","idempotencyKey":"test-1","reasoning":"test","tokenAddress":"So11111111111111111111111111111111111111112"}
```
## Inbound canonicalization rules
1. Only signing-eligible keys are included (`text`, `idempotencyKey`, and structured fields from the `#1098` schema).
2. Object keys are sorted alphabetically at every nesting level.
3. Unknown top-level fields are **omitted** from the canonical form.
4. Numbers must be finite JSON numbers (no `NaN` / `Infinity`).
Match the SDK implementation: [`inbound_canonical.rs`](https://github.com/EchoZeroApp/echozero-sdk/blob/main/packages/rust/src/inbound_canonical.rs) (reference for all languages).
## Outbound `signal.execution`
| Field | Value |
| ------------------------------- | ----------------------------------------------------------------------------------------------------------------------------------------- |
| Secret | `webhook_secret` |
| Timestamp | `2026-07-06T12:00:00.000Z` |
| Raw body | `{"event":"signal.execution","signalId":"sig_1","developerAgentId":"agent_1","status":"executed","timestamp":"2026-07-06T12:00:00.000Z"}` |
| Payload | `{timestamp}.{raw_body}` |
| Algorithm | HMAC-SHA256 → lowercase hex |
| Expected `x-echozero-signature` | `249d84b9e89206f6aee4b124f728c945b805666b3102d76b913a17f1bf568574` |
Verify with the same raw bytes you receive on the wire (do not re-serialize JSON).
## Inbound webhook (nested buy with triggers + context)
| Field | Value |
| ------------------------- | ------------------------------------------------------------------ |
| Secret | `test_secret` |
| Timestamp (s) | `1710000000` |
| Canonical JSON | see below |
| Expected `X-EZ-Signature` | `3afa3bf158361edcb46dbeaee6b128f7cd1c78baa28824f2355de1223671e67a` |
```json theme={null}
{"amount":500,"chain":"solana","context":{"indicators":["VWAP","RSI"],"marketCondition":"trending","price":148.5},"eventType":"buy","idempotencyKey":"nested-vector-001","instrument":{"tokenAddress":"So11111111111111111111111111111111111111112"},"reasoning":"Nested canonicalization test.","symbol":"SOL","triggers":{"slPrice":{"targetType":"price","value":165},"tps":[{"label":"TP1","sizePct":50,"targetType":"price","value":180}]}}
```
Nested objects must be sorted at every level (`slPrice` before `tps`; `targetType` before `value` inside each TP). This is where cross-language signing bugs usually appear.
## curl self-test (REST)
```bash theme={null}
SECRET="test_secret"
TS="1710000000000"
REQ_PATH="/api/api-keys"
BODY='{"name":"SDK HMAC Test"}'
SIG=$(printf '%s' "${TS}POST${REQ_PATH}${BODY}" | openssl dgst -sha256 -hmac "$SECRET" | awk '{print $2}')
echo "$SIG"
# expect 274c9ff280eadf751530e9e7fce2c2a573d8676b13b7108fe353407df7cc9e00
```
# Versioning policy
Source: https://docs.echozero.app/guides/versioning
How EchoZero versions the REST API and announces breaking changes.
## Current version
The public REST API is **`v1`** (`/api/v1/...`). The OpenAPI document version tracks the deployment (`1.0` in `docs-json`).
## Signal schema version
Structured signal envelopes include optional `version` (currently **`1`**, issue `#1098`). New event types and fields are additive within the same major version.
## Change categories
| Type | Policy |
| -------------- | -------------------------------------------------------------------------------------------------------- |
| **Additive** | New endpoints, optional JSON fields, new enum values: no notice required |
| **Behavioral** | Execution rule changes: announced in [Changelog](/changelog) |
| **Breaking** | Removed fields, renamed paths, auth changes: 30-day notice in changelog + email to registered developers |
## What we consider breaking
* Removing or renaming a published `/v1` path
* Requiring a previously optional field on inbound signals
* Changing HMAC signing algorithms without a new header/version
* Tightening default rate limits below published tiers
## What is not breaking
* New `skipReason` or error codes
* New MCP tools or scopes (existing keys keep working)
* Internal admin endpoint changes (not in public OpenAPI)
## Staying updated
* [Changelog](/changelog) (dated entries)
* `GET https://mcp.echozero.app/api/docs-json` (machine-readable)
* Register in the Dev Portal for operational emails
## MCP protocol version
MCP clients should send `protocolVersion: "2025-03-26"` (or newer supported) in `initialize`. See [MCP Server](/guides/mcp).
# Webhook security
Source: https://docs.echozero.app/guides/webhook-security
Verify inbound provider webhooks, agent signal ingress, and outbound execution callbacks.
EchoZero uses **three distinct signing schemes** depending on direction and transport. Using the wrong algorithm is the most common integration mistake.
| Direction | Headers | Timestamp | Payload signed |
| --------------------------- | ---------------------------------------------- | ----------------- | ---------------------------------- |
| REST API | `x-signature`, `x-timestamp` | Epoch **ms** | `timestamp + METHOD + path + body` |
| Inbound agent signals | `X-EZ-Signature`, `X-EZ-Timestamp` | Epoch **seconds** | `timestamp + "." + canonicalJson` |
| Outbound `signal.execution` | `x-echozero-signature`, `x-echozero-timestamp` | ISO in payload | `timestamp + "." + jsonBody` |
## Inbound agent HTTP signals
**Endpoint:** `POST https://mcp.echozero.app/api/public/agent-signals/{agentId}`
No developer API key. Authenticate with the per-agent signing secret (`ezw_...`) revealed once at provision or rotation.
**Always send a stable `idempotencyKey` on every inbound signal**, including natural-language `text` and legacy payloads. Without it, a captured or retried signed request can execute the trade again. See [Signal envelope](/guides/signal-envelope).
### Headers
| Header | Required | Description |
| ---------------- | -------- | ------------------------- |
| `Content-Type` | Yes | `application/json` |
| `X-EZ-Timestamp` | Yes | Unix time in **seconds** |
| `X-EZ-Signature` | Yes | Lowercase hex HMAC-SHA256 |
### Signing algorithm
1. Serialize the request body as **canonical JSON** - keys sorted alphabetically at every object level, `undefined` fields omitted.
2. Build: `payloadString = "${unixSeconds}.${canonicalJson}"`
3. Sign: `HMAC_SHA256(signingSecret, payloadString)` → lowercase hex
```bash theme={null}
SECRET='ezw_...'
TS=$(date +%s)
CANON='{"text":"BUY SOL 500 USDC"}'
PAYLOAD="$TS.$CANON"
SIG=$(printf '%s' "$PAYLOAD" | openssl dgst -sha256 -hmac "$SECRET" | awk '{print $2}')
curl -X POST "https://mcp.echozero.app/api/public/agent-signals/$AGENT_ID" \
-H "Content-Type: application/json" \
-H "X-EZ-Timestamp: $TS" \
-H "X-EZ-Signature: $SIG" \
-d '{"text":"BUY SOL 500 USDC"}'
```
### SDK helpers
The [echozero-sdk](https://github.com/EchoZeroApp/echozero-sdk) provides `signInboundWebhook` / `sign_inbound_webhook` in TypeScript, Python, Go, and Rust with canonical JSON built in.
```typescript theme={null}
import { signInboundWebhook } from '@echozero/sdk';
const body = { text: 'BUY SOL 500 USDC' };
const headers = await signInboundWebhook({
signingSecret: process.env.EZW_SECRET!,
body,
});
// headers['X-EZ-Timestamp'], headers['X-EZ-Signature']
```
### Replay protection
* Requests with timestamp skew beyond **±5 minutes** are rejected with **401**.
* Use a unique `idempotencyKey` per signal so retries are safe no-ops.
### Verify inbound (Python)
```python theme={null}
import hmac, hashlib, json
def verify_inbound(secret: str, body: dict, timestamp: str, signature: str) -> bool:
# Use SDK canonical_json in production; see signature test vectors
from echozero.hmac import canonical_webhook_body # when SDK published
canon = json.dumps(body, sort_keys=True, separators=(",", ":"))
payload = f"{timestamp}.{canon}"
expected = hmac.new(secret.encode(), payload.encode(), hashlib.sha256).hexdigest()
return hmac.compare_digest(expected, signature)
```
Golden vectors: [Signature test vectors](/guides/signature-test-vectors).
## Outbound execution webhooks
When your agent has a `webhookUrl`, EchoZero POSTs execution results after trade attempts.
### Signing secret
Use the **agent webhook signing secret** configured on the agent (`webhookUrl` + secret pair). Rotate by updating the agent record in Dev Portal or `PATCH /api/v1/agents/{id}`.
### Delivery contract
| Property | Value |
| -------- | --------------------------------------------------------------------- |
| Method | `POST` |
| Timeout | **10 seconds** |
| Retries | **None** (single attempt; implement idempotent handling on your side) |
| Events | `signal.execution`, `signal.execution.failed` |
### Event catalog
```json theme={null}
{
"event": "signal.execution",
"signalId": "...",
"developerAgentId": "...",
"status": "executed",
"executionResult": {
"success": true,
"txHash": "...",
"executedAmountUsd": 100,
"executedAt": "2026-07-06T12:00:00.000Z"
},
"timestamp": "2026-07-06T12:00:00.000Z"
}
```
### Verify on your server
Headers:
| Header | Description |
| ---------------------- | ----------------------------------------------------------- |
| `x-echozero-timestamp` | Same ISO timestamp as payload `timestamp` field |
| `x-echozero-signature` | `HMAC_SHA256(webhookSecret, timestamp + "." + rawJsonBody)` |
```python theme={null}
import hmac, hashlib
def verify_outbound(secret: str, raw_body: bytes, timestamp: str, signature: str) -> bool:
payload = f"{timestamp}.{raw_body.decode()}"
expected = hmac.new(secret.encode(), payload.encode(), hashlib.sha256).hexdigest()
return hmac.compare_digest(expected, signature)
```
Reject requests outside a 5-minute timestamp window and treat duplicate `signalId` deliveries as idempotent.
## Provider webhooks (Telegram, Discord)
When EchoZero hosts signal ingestion for Telegram or Discord bots, provider-specific secrets apply. These routes do **not** use developer API keys.
### Telegram
**Endpoint:** `POST /api/webhooks/telegram/signal-bot`
When the server has `SIGNAL_TELEGRAM_WEBHOOK_SECRET` configured, every request must include:
```
X-Telegram-Bot-Api-Secret-Token:
```
Configure this when registering your bot webhook via Telegram's `setWebhook` API.
### Discord
**Endpoint:** `POST /api/webhooks/discord/signal-bot`
When `SIGNAL_DISCORD_WEBHOOK_SECRET` is set:
```
X-Discord-Signal-Webhook-Secret:
```
Used when Discord Gateway ingest is off or for webhook-based testing.
## REST API HMAC (developer routes)
For authenticated developer API calls (`/api/v1/*`), HMAC uses your **API secret** with millisecond timestamps and method+path signing. See [API keys and HMAC](/guides/api-keys-hmac).
Do **not** use REST API HMAC headers (`x-signature` / `x-timestamp`) on inbound agent signal POSTs. Agent ingress requires `X-EZ-Signature` / `X-EZ-Timestamp` with the per-agent `ezw_` secret.
## Security checklist
* Store signing secrets in a secrets manager - they are shown only once at creation/rotation.
* Use HTTPS for all webhook URLs.
* Enforce timestamp windows on every inbound webhook you receive.
* Deduplicate by `idempotencyKey` (inbound) or `signalId` (outbound).
* Rotate compromised secrets via `rotateInboundWebhookSigningSecret` or API key revocation in the Dev Portal.
# WebSocket signal gateway
Source: https://docs.echozero.app/guides/websocket-gateway
Stream signals over Socket.IO with your developer API key.
The WebSocket gateway lets your engine push signals with lower latency than HTTP webhooks. It uses the **same JSON schema** as inbound webhooks and the developer API.
## Endpoint
```
wss://mcp.echozero.app/ws/signals
```
Socket.IO namespace: `/ws/signals`
## Authentication
Pass your developer API key in the Socket.IO handshake:
* Header: `x-api-key: ez_live_...`, or
* Auth payload: `{ "apiKey": "ez_live_..." }`
Connection-level HMAC is **not** used on WebSocket. REST API-key requests require request signing; protect credentials in transit (TLS only).
Invalid or missing keys receive an `error` event and disconnect.
## Send a signal
Emit event `signal` with payload:
```json theme={null}
{
"developerAgentId": "674a1b2c3d4e5f6789012345",
"text": "BUY SOL $100",
"idempotencyKey": "ws-entry-001"
}
```
Structured `#1098` payloads work the same as [Signal envelope](/guides/signal-envelope) (include `eventType`, `reasoning`, `idempotencyKey`).
## Responses
| Event | Meaning |
| -------------- | -------------------------- |
| `signal:ack` | Accepted for processing |
| `signal:error` | Validation or auth failure |
## Rate limits
Connection inherits your API key rate limit tier (60/300/1000 req/min on REST; burst behavior on WebSocket is enforced server-side). Use `idempotencyKey` on every message.
## Reconnect pattern
1. Reconnect with the same API key
2. Re-send unacknowledged signals with the **same** `idempotencyKey`
3. Do not assume ordering across reconnects
## vs HTTP webhook
| | WebSocket | Webhook |
| --------- | --------------- | ----------------------------------------------- |
| Auth | API key | Per-agent `ezw_` HMAC |
| Direction | You connect out | EchoZero POSTs to you (outbound callbacks only) |
| Schema | Same | Same |
## SDK (coming soon)
The echozero-sdk WebSocket client wraps connect, `signal` emit, and reconnect. See [SDK](/guides/sdk).
# Introduction
Source: https://docs.echozero.app/index
Build, connect, and operate trading agents on EchoZero with REST, MCP, and webhooks.
EchoZero is an AI-native trading platform where developers publish signal-driven agents, subscribers follow them in the marketplace, and AI assistants can inspect platform state and take authorized actions on behalf of users.
Use this documentation to integrate with the EchoZero API: authenticate, send signals, manage agents, and operate wallets and strategies programmatically.
## How it works
```mermaid theme={null}
flowchart LR
A[Your bot / strategy] -->|signal| B[EchoZero ingest]
B --> C[Execution]
C --> D[Subscribers]
D --> E[Fees & payouts]
```
1. You publish an **agent** and connect a signal source (webhook, WebSocket, Telegram, Discord).
2. Subscribers opt in via the marketplace.
3. Each accepted signal fans out into per-subscriber trades.
4. You earn via success fees and/or subscriptions.
[Read the full loop →](/concepts/how-it-works)
## What you can build
* **[Signal bots](/tutorials/first-agent)** that post structured or natural-language trade signals to EchoZero agents.
* **[MCP clients](/guides/mcp)** that let Claude, ChatGPT, Cursor, and other assistants call EchoZero tools with OAuth or API keys.
* **[Marketplace agents](/guides/earnings)** with subscriber analytics, earnings, and payout flows.
* **[Webhook receivers](/guides/webhook-security)** that verify inbound and outbound events with HMAC.

curl -sS https://mcp.echozero.app/mcp \
-H "x-api-key: $EZ_API_KEY" \
-H "Content-Type: application/json" \
-H "mcp-session-id: $MCP_SESSION_ID" \
-d '{
"jsonrpc": "2.0",

}'
```
Resources return JSON text suitable for model context. They respect the same scopes as the equivalent REST routes.
## Prompts vs resources
* **Resources** = static URI-addressable snapshots
* **Prompts** = templated multi-step instructions (`prompts/get`)
See [MCP tools](/mcp/tools) for the full tool catalog.
# MCP tools reference
Source: https://docs.echozero.app/mcp/tools
Catalog of MCP tools exposed at tools/list, grouped by domain and scope.
EchoZero exposes **70+ MCP tools** plus resources and prompts. Tools forward to the same REST endpoints as the [API Reference](/api-reference). Call `tools/list` after [MCP initialize](/guides/mcp) for the live list scoped to your API key.

"name": "get_my_agents",
"arguments": {}
}
}'
```
## Prompts
Built-in prompts: `analyze_strategy_performance`, `portfolio_overview`, `token_research`, `create_trading_strategy`. Call `prompts/list` and `prompts/get`.
## Resources
Read-only `echozero://` URIs are documented on [MCP Resources](/mcp/resources).
# Quickstart
Source: https://docs.echozero.app/quickstart
Authenticate and send your first signal in under 5 minutes.
Get from zero to a signed API call and optional test signal. For the full end-to-end path, start with [Build your first agent](/tutorials/first-agent).
## Choose your path
| Persona | Start here |
| ------------------------------- | ------------------------------------------------------------ |
| Signal bot / webhook integrator | Steps below → [first-agent tutorial](/tutorials/first-agent) |
| AI assistant (Claude, ChatGPT) | [OAuth](/guides/oauth) or [MCP](/guides/mcp) |
| Telegram / Discord operator | [Signal groups](/guides/signal-groups) |
## Step 0: Get your API key
1. Sign in at [devportal.echozero.app](https://devportal.echozero.app)
2. Register as a developer
3. Create an API key
4. Copy **`ez_live_...`** and **`ezs_...`** (secret shown once)
```bash theme={null}
export EZ_API_KEY="ez_live_..."
export EZ_SECRET="ezs_..."
```
## Step 1: Verify the API
```bash theme={null}
curl -sS https://mcp.echozero.app/api
```
```json theme={null}
{ "success": true, "data": { "status": "ok" } }
```
## Step 2: Authenticate
```bash theme={null}
curl -sS https://mcp.echozero.app/api/v1/users/me \
-H "x-api-key: $EZ_API_KEY"
```
**Expected:**
```json theme={null}
{
"success": true,
"data": {
"id": "...",
"email": "you@example.com"
}
}
```
You are authenticated when `success` is `true` and `data.id` is present.
Getting **401**? See [Error codes](/guides/error-codes).
## Step 3: Create a webhook agent (optional)
```bash theme={null}
curl -sS -X POST https://mcp.echozero.app/api/v1/agents \
-H "x-api-key: $EZ_API_KEY" \
-H "Content-Type: application/json" \
-d '{
"name": "Quickstart Agent",
"signalSourceKind": "webhook"
}'
```
**Expected:**
```json theme={null}
{
"success": true,
"data": {
"id": "674a1b2c3d4e5f6789012345",
"name": "Quickstart Agent",
"signalSourceKind": "webhook",
"betaStatus": "pending-review",
"inboundWebhookSigningSecretReveal": "ezw_...",
"inboundSignalsHttpUrl": "https://mcp.echozero.app/api/public/agent-signals/674a1b2c3d4e5f6789012345"
}
}
```
Save `inboundWebhookSigningSecretReveal` (`ezw_...`) from the response.
## Step 4: Send a test signal
Requires agent in `beta` or `public`. Use [virtual wallet](/guides/sandbox) while in review.
```bash theme={null}
export AGENT_ID=""
export EZW_SECRET=""
TS=$(date +%s)
CANON='{"text":"BUY SOL $50","idempotencyKey":"quickstart-001"}'
SIG=$(printf '%s' "$TS.$CANON" | openssl dgst -sha256 -hmac "$EZW_SECRET" | awk '{print $2}')
curl -sS -X POST "https://mcp.echozero.app/api/public/agent-signals/$AGENT_ID" \
-H "Content-Type: application/json" \
-H "X-EZ-Timestamp: $TS" \
-H "X-EZ-Signature: $SIG" \
-d '{"text":"BUY SOL $50","idempotencyKey":"quickstart-001"}'
```
**Success:**
```json theme={null}
{
"success": true,
"data": {
"outcome": "matched",
"signalId": "sig_..."
}
}
```
## Step 5: Explore further
Curated OpenAPI docs and try-it console.
Download the machine-readable spec.
Event types and structured payloads.
HMAC signing and replay protection.
## Assistant setup (coming soon)
**Coming soon:** The public skills pack (`EchoZeroApp/skills`) and `ez login` CLI are not yet available. Use [OAuth](/guides/oauth) or API keys until the skills repo is published.
```bash theme={null}
# When available:
npx skills add EchoZeroApp/skills
ez login
```
# Hyperliquid perp with SL/TP ladder
Source: https://docs.echozero.app/recipes/hyperliquid-perp
Structured buy signal for a Hyperliquid perpetual with triggers.
```json theme={null}

]
}
}
```
Sign with per-agent HMAC and POST to `/api/public/agent-signals/{agentId}`.
Hyperliquid is unavailable in [virtual wallet mode](/guides/sandbox); test lifecycle parsing in sandbox simulate endpoints first.

When published, use `echozero.sign_inbound_webhook` from the [SDK](/guides/sdk) instead of inline canonicalization.
# Relay a Telegram signal group
Source: https://docs.echozero.app/recipes/telegram-relay
Connect a Telegram channel to an EchoZero signal-group agent.
1. Create agent with `signalSourceKind: signal_group` ([tutorial](/tutorials/first-agent))
2. `GET /api/v1/agents/telegram/bot-metadata` for bot username
3. Add the EchoZero bot as admin to your channel
4. `POST /api/v1/agents/{id}/telegram/verify` with `{ "channelUsername": "@YourChannel" }`
5. Post `BUY SOL $500 TP 180 SL 165` in the channel
6. Monitor `GET /api/v1/developers/agents/{id}/signals/ingest-log`
See [Signal groups](/guides/signal-groups) and [Signal grammar](/guides/signal-grammar).
# Forward TradingView alerts
Source: https://docs.echozero.app/recipes/tradingview-alerts
Send TradingView webhook alerts to an EchoZero inbound agent URL.
TradingView cannot sign EchoZero canonical JSON natively. Use a small relay (Cloudflare Worker, AWS Lambda, or your server) that receives TradingView's POST, maps fields to EchoZero, signs with your agent's `ezw_` secret, and forwards to `inboundSignalsHttpUrl`.
## TradingView alert message (example)
```
BUY {{ticker}} @ {{close}}
```
Configure the webhook URL to point at your relay, not directly at EchoZero.
## Relay (Node.js)
```javascript theme={null}

```
## SDK helper (when published)
When `@echozero/sdk` ships to npm, replace manual signing with `signInboundWebhook` from the [SDK guide](/guides/sdk). Until then, use [Signature test vectors](/guides/signature-test-vectors) or the canonicalizer above.
Always set `idempotencyKey` from TradingView's `alert_id` or `timenow` so retries do not double-execute.

Risk disclosure and acceptable use for signal providers on EchoZero.
EchoZero is a **custodial, real-money trading platform**. Developers who publish agents and send trade signals must understand subscriber risk and regulatory constraints.
## Your responsibilities
* Signals may execute real trades on subscriber wallets
* You are responsible for signal accuracy, timeliness, and disclosure
* Test with [virtual wallet mode](/guides/sandbox) before going live
* Use [idempotency keys](/guides/signal-envelope) on every signal
## Platform terms
* [Terms of Service](https://mcp.echozero.app/public/terms-of-service.md)
* [Privacy Policy](https://mcp.echozero.app/public/privacy-policy.md)
## Geographic restrictions
EchoZero blocks access from certain jurisdictions (including US, UK, and Ontario for restricted features). Do not circumvent geo controls or onboard ineligible subscribers.
## Prohibited use
* Market manipulation or pump-and-dump schemes
* Sharing API keys or signing secrets in client-side code
* Bypassing review or publishing agents without required disclosures
* Sending signals without subscriber consent mechanisms required by law
## Risk disclosure for subscribers
Paid agents should clearly state:
* Past performance is not indicative of future results
* Crypto trading involves total loss risk
* Success fees and subscriptions are charged per your published pricing

# Build your first agent
Source: https://docs.echozero.app/tutorials/first-agent
Create a webhook agent, fund a virtual wallet, send a signed signal, and see outcome matched.
This tutorial walks through the full integration path: developer account → webhook agent → virtual wallet → signed signal → lifecycle event.
**Time:** \~15 minutes\
**Prerequisites:** [Dev Portal](https://devportal.echozero.app) account
## 1. Register and create an API key
Sign in at [devportal.echozero.app](https://devportal.echozero.app), register as a developer, and create an API key. Copy **`ez_live_...`** and **`ezs_...`** immediately (the secret is shown once).
```bash theme={null}
export EZ_API_KEY="ez_live_..."
export EZ_SECRET="ezs_..."
```
You have a developer API key pair saved locally.
## 2. Create a webhook agent
```bash theme={null}
curl -sS -X POST https://mcp.echozero.app/api/v1/agents \
-H "x-api-key: $EZ_API_KEY" \
-H "Content-Type: application/json" \
-d '{
"name": "Tutorial Webhook Agent",
"description": "First integration test",
"signalSourceKind": "webhook",
"isDraft": false
}'
```
**Expected response (abbreviated):**
```json theme={null}
{
"success": true,
"data": {
"id": "674a1b2c3d4e5f6789012345",
"name": "Tutorial Webhook Agent",
"signalSourceKind": "webhook",
"betaStatus": "pending-review",
"inboundWebhookSigningSecretReveal": "ezw_...",
"inboundSignalsHttpUrl": "https://mcp.echozero.app/api/public/agent-signals/674a1b2c3d4e5f6789012345"
}
}
```
Save `inboundWebhookSigningSecretReveal` (`ezw_...`) now. It is never returned again. Rotate via `PATCH /api/v1/agents/{id}` with `{ "rotateInboundWebhookSigningSecret": true }` if lost.
```bash theme={null}
export AGENT_ID=""
export EZW_SECRET=""
```
Signals execute only when `betaStatus` is `beta` or `public`. For sandbox testing, use [virtual wallet mode](#4-enable-virtual-wallet) and the [sandbox endpoints](/guides/sandbox) while your agent is in review, or ask your platform admin to approve the agent to beta.
## 3. Enable virtual wallet
```bash theme={null}
curl -sS -X POST https://mcp.echozero.app/api/v1/wallet/mode \
-H "x-api-key: $EZ_API_KEY" \
-H "Content-Type: application/json" \
-d '{ "isVirtualMode": true }'
```
```json theme={null}
{ "success": true, "data": { "isVirtualMode": true } }
```
```bash theme={null}
curl -sS -X POST https://mcp.echozero.app/api/v1/wallet/virtual/add-funds \
-H "x-api-key: $EZ_API_KEY" \
-H "Content-Type: application/json" \
-d '{ "amountInSol": 10 }'
```
## 4. Send a signed entry signal
```bash theme={null}
TS=$(date +%s)
CANON='{"text":"BUY SOL $100","idempotencyKey":"tutorial-entry-001"}'
SIG=$(printf '%s' "$TS.$CANON" | openssl dgst -sha256 -hmac "$EZW_SECRET" | awk '{print $2}')
curl -sS -X POST "https://mcp.echozero.app/api/public/agent-signals/$AGENT_ID" \
-H "Content-Type: application/json" \
-H "X-EZ-Timestamp: $TS" \
-H "X-EZ-Signature: $SIG" \
-d '{"text":"BUY SOL $100","idempotencyKey":"tutorial-entry-001"}'
```
**Expected when agent is beta/public:**
```json theme={null}
{
"success": true,
"data": {
"outcome": "matched",
"signalId": "sig_...",
"status": "..."
}
}
```
You received `outcome: matched` and a `signalId`. That is the success moment.
If the agent is still `pending-review`, you may see `outcome: skipped` with `skipReason` containing `agent_status_blocked`.
## 5. Send a lifecycle partial sell (optional)
```bash theme={null}
TS=$(date +%s)
CANON='{"eventType":"partial_sell","idempotencyKey":"tutorial-partial-001","positionRef":"tutorial-entry-001","sellSizePct":50,"reasoning":"Taking half off at first target."}'
SIG=$(printf '%s' "$TS.$CANON" | openssl dgst -sha256 -hmac "$EZW_SECRET" | awk '{print $2}')
curl -sS -X POST "https://mcp.echozero.app/api/public/agent-signals/$AGENT_ID" \
-H "Content-Type: application/json" \
-H "X-EZ-Timestamp: $TS" \
-H "X-EZ-Signature: $SIG" \
-d "$CANON"
```
## 6. Check signal history
```bash theme={null}
curl -sS "https://mcp.echozero.app/api/v1/developers/agents/$AGENT_ID/signals/history?page=1&limit=10" \
-H "x-api-key: $EZ_API_KEY"
```
