## 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. |
| 404 | [not_found](https://upfour.io/docs/api/errors#code-not_found) | The requested resource does not exist or is outside the caller's scope. |

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).
