## Rate Limit

* **100 requests per minute, per API key.** Fixed 60-second window.
* Every response includes `X-RateLimit-Limit`, `X-RateLimit-Remaining`, and `X-RateLimit-Reset` (unix epoch seconds).
* A `429` response includes a `Retry-After` header (seconds until the bucket resets).

For client-side patterns (`Retry-After`, exponential backoff, monitoring `X-RateLimit-Remaining`), see [Rate Limiting](/rate-limiting).
