## Verdicts

**Beatoven.ai API.** Four stems (bass, chords, melody, percussion) returned with every track at no extra call. No API price, free tier or rate limits published.

**Google Lyria.** $0.08 a full song on `lyria-3.5` and $0.04 a 30-second clip, flat. No free tier for Lyria, so billing is needed before the first call.

## Before you call either

### Beatoven.ai API

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

### Google Lyria

1. Draft on `lyria-3-clip-preview` at $0.04 before paying for a full song
2. Put the target length and structure in the prompt, e.g. "[0:00 - 0:10] Intro" or "a 2-minute song"
3. Decode `output_audio.data` from base64 straight to a file. Don't let it into the context
4. Don't name artists or paste song lyrics. The safety filter blocks the request
5. Back off exponentially on 429 `RESOURCE_EXHAUSTED`. Limits are per project and tier
