# Status and Error Codes

The CryptoQuant API uses standard HTTP status codes to indicate success or failure. 200 represents success, 4xx represents a user error (such as a problem with your key), and 5xx represents a problem with our API.

The following table describes status and error codes returned by API. In the status object, the `code` field contains the status code and the `message` field contains the type of response.

| Code  | Type                    | Description                                                                                                                       |
