# Audio models

Music (Suno) and text-to-speech (Gemini TTS) models use the same /generations flow as images and video: create a task, then poll it. Outputs are audio file URLs.

## cURL

```bash
curl 'https://01router.com/api/v1/generations' \
  -H "Authorization: Bearer $API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
  "model": "gemini-3.8-flash-tts",
  "input": {
    "prompt": "Welcome back, let us get started.",
    "voice": "Kore"
  }
}'
```

## Usage notes

- Poll at intervals of at least 3 seconds. A 504 from the synchronous image endpoint means the task may still be running: poll its error.id instead of submitting it again.
