## Errors

Only the errors this operation can return. Every error uses the [same envelope](https://upfour.io/docs/api/responses.md).

| Status | Code | Meaning |
| --- | --- | --- |
| 400 | [bad_request](https://upfour.io/docs/api/errors#code-bad_request) | The request is malformed or fails validation. |
| 402 | [billing_action_unavailable](https://upfour.io/docs/api/errors#code-billing_action_unavailable) | The Company's billing state does not allow this action. **When:** A metered or limited action while the billing state, such as paused or without credit, blocks it; details holds the action and billing_state. **Fix:** Top up the credit or change the plan, then retry. |
| 403 | [permission_denied](https://upfour.io/docs/api/errors#code-permission_denied) | The credentials do not permit this action. |
| 503 | [quota_gate_unavailable](https://upfour.io/docs/api/errors#code-quota_gate_unavailable) | The limit check itself failed, so the action was not carried out. **When:** The quota service could not decide while the request ran. **Fix:** Retry in a moment; nothing was changed. |
| 403 / 429 | [quota_limit_reached](https://upfour.io/docs/api/errors#code-quota_limit_reached) | The protection limit for this action is used up; retry after the response's `Retry-After` delay. **When:** Counters and concurrency limits answer 429 with Retry-After, inventory and capacity limits answer 403; details holds purpose, limit and window. **Fix:** On 429 wait Retry-After seconds; on 403 free something up, request a higher limit where details.raise_request is true, or buy an extension. `quota_limit_reached`: the protection limit of this action is used up for now. `error.details` carries `purpose`, `limit`, `window` and `retry_after_seconds`; the `Retry-After` header says when the same request can succeed. |

Every call can also return `unauthorized` (401), `rate_limit_exceeded` (429) or `internal_error` (500 / 502). See [Responses and errors](https://upfour.io/docs/api/responses.md).
