## Rate Limit

- **300 requests per minute, shared by every `read` call in your workspace.** Fixed 60-second window.
- Every response includes `X-RateLimit-Limit`, `X-RateLimit-Remaining`, `X-RateLimit-Reset` (unix epoch seconds) and `X-RateLimit-Bucket` (`read`).
- A `429` response includes a `Retry-After` header (seconds until the bucket resets).
