### Errors

Errors return an `ok: false` envelope. Rate limiting returns `429` with `x-rate-limit-limit`, `x-rate-limit-remaining` and `x-rate-limit-reset` headers. `x-rate-limit-reset` is the number of seconds until the window reopens. `Retry-After` is not sent, so schedule retries from `x-rate-limit-reset`; retrying sooner will fail again.

```json
{ "ok": false, "message": "Unauthorized", "code": "UNAUTHORIZED" }
```

Rate limits for this version: enforced per endpoint; ceilings are not published and can change without notice. A `429` response carries `x-rate-limit-limit`, `x-rate-limit-remaining`, and `x-rate-limit-reset` (seconds until the window reopens). Back off from those headers rather than hardcoding numbers. If you need sustained throughput, prefer batching (operations like `/createTask` accept arrays) over tightening polling loops. See [Rate limits](https://www.taskade.com/docs/getting-started/action-api-guide#rate-limits).
