# Errors

> Blockradar's API is RESTful and as such, uses conventional HTTP response codes to indicate the success or failure of requests.

### HTTP Codes

| Code | Description                                                                                                                                               |
| ---- | --------------------------------------------------------------------------------------------------------------------------------------------------------- |
| 200  | Request was successful and intended action was carried out.                                                                                               |
| 201  | A resource has successfully been created.                                                                                                                 |
| 400  | A validation or client side error occurred and the request was not fulfilled.                                                                             |
| 401  | The request was not authorized. This can be triggered by passing an invalid api key in the x-api-key header or the lack of one.                           |
| 404  | Request could not be fulfilled as the requested resource does not exist.                                                                                  |
| 5xx  | Request could not be fulfilled due to an error on Blockradar's end. This shouldn't happen so please report as soon as you encounter any instance of this. |
