      description: 'The MX Platform API requires basic access authentication using your `client_id` and `api_key`. These credentials must be Base64 encoded and included in the Authorization header of each API request to ensure secure access.


        Here''s an example using curl to access `v20250224`. Replace `https://int-api.mx.com/endpoint` with the actual API endpoint you wish to access and your Base64 encoded `client_id` and `api_key`.


        ```

        curl -L -X POST `https://int-api.mx.com/endpoint'' \
