## Errors

| Status | Description |
|--------|-------------|
| `401` | Missing, invalid, revoked or expired API key |

## Rate Limit

- **120 requests per minute, shared by every `write` 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` (`write`).
- A `429` response includes a `Retry-After` header (seconds until the bucket resets).
