# Errors

Our Premium Bank API uses standard HTTP response codes to indicate the success or failure of requests. Codes in the `2xx` range indicate success; codes in the `4xx` and `5xx` ranges indicate errors. The format of error messages is unified and can be distinguished by their `code` key. The `message` provides a plain English explanation of the problem.


## Example
```json
{
  "code": "error_code",
  "message": "Example error message.",
}
```
