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
curl -X POST "https://api.suonora.com/v1/audio/speech" \
     -H "Authorization: Bearer YOUR_API_KEY" \
     -H "Content-Type: application/json" \
     -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.
