## Before you call it

1. Submit to `queue.fal.run` and poll or use a webhook. Synchronous `fal.run` calls went down for 30 minutes on 2026-09-04
2. Check the unit on the model page. ElevenLabs v2.5 bills a whole minute for a 30-second clip
3. Pin the versioned endpoint, for example `fal-ai/elevenlabs/music/v2.5`
4. Use an API-scope key for agents, never an ADMIN key
5. For stems, run `fal-ai/demucs` on the output

## Connect

```bash
curl -X POST https://queue.fal.run/fal-ai/lyria2 -H "Authorization: Key $FAL_KEY" \
  -H "Content-Type: application/json" -d '{"prompt":"lo-fi hip-hop beat with mellow piano"}'
```
