## Using Model IDs

When making a request to the Suonora TTS API, specify the short name of the model under the `model` field. Ensure your subscription plan grants you access to that model.

**Example Request**:

```sh request.sh
curl -X POST "https://api.suonora.com/v1/audio/speech" \
     -H "Authorization: Bearer YOUR_API_KEY" \
     -H "Content-Type: application/json" \
     --output output.mp3 \
     -d '{
       "input": "Hello, welcome to Suonora!",
       "model": "legacy-v2.5",
       "voice": "axel"
     }'
```

Replace the `model` value with any of the available short names (e.g., `legacy-prime`, `sonic-speed`, etc.), and confirm that your plan supports it.
