### 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. Bundle import and export run under tighter limits than regular reads and writes, so schedule bulk transfers accordingly. See [Rate limits](https://www.taskade.com/docs/getting-started/rest-api-guide#rate-limits).
