## Errors

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

The specification does not list additional operation-specific errors.

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).
