# API Registration

> How to register your own API in API-based evaluation

You can register your own voice AI model API and compare it with our provided APIs to evaluate model performance using the wizard.

<Warning>
  Your API must return response data in one of the following formats:

  * Binary data (audio file)
  * JSON with base64-encoded audio file data stored in the `audioContent` field

    Example:

    ```json theme={null}
    {
      "audioContent": "//NEXAASSL5UAHpMTAJdcPZ6MCsePBW3MLg..."
    }
    ```
