## API Usage

The public [Developer API](https://miaodashi.com/api-platform) page lists the available image and video models. Different models and generation settings consume different amounts of credit; use the amount shown during generation as the final reference.

To call the API:

1. Sign in and open [API Keys](https://miaodashi.com/account/api-keys).
2. Create an API key and store it securely.
3. Send it in the `Authorization: Bearer <YOUR_API_KEY>` header.

See the [API Overview](/api-reference/introduction) for request examples and endpoint documentation.
