    **Rate Limiting:** All endpoints enforce per-API-key rate limits. Tiers:
    free (60 req/min), standard (300 req/min), premium (1000 req/min). Every
    response includes `X-RateLimit-Limit`, `X-RateLimit-Remaining`,
    `X-RateLimit-Reset` headers. Exceeding the limit returns `429 Too Many
    Requests` with a `Retry-After` header.
