## Before you call it

1. Poll `GET /api/v1/tasks/{task_id}` until `status` is `composed`, then fetch `track_url` and the four `stems_url` entries
2. Put the length in the prompt text, e.g. "30 seconds peaceful lo-fi". There's no duration field
3. Set `format` to `mp3`. The default is WAV
4. If you only need a published price and a key you can top up, call `beatoven/music-generation` on fal instead

## Connect
