## 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.

**MusicGPT API.** A public OpenAPI 3.1 file with 27 operations, llms.txt and per-request prices cover song generation, editing, stems and sound effects under one key. No status page, SLA, security.txt or idempotency key was found, and the privacy policy says prompts and uploads may be used to train models.

## 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

### MusicGPT API

1. Send the key as the raw `Authorization` header value. The docs show no `Bearer` prefix
2. Budget two songs for each music request. `POST /v2/MusicAI` returns two versions and the price is per song
3. Save `task_id` and poll `GET /v1/byId` with `conversionType`, or set `webhook_url`. Music AI V2 sends up to seven webhooks a request
4. Pass `model` explicitly. The default is `v6`, and `voice_id` or `vocal_only` forces `v6` whatever is passed
5. Do not retry a create blindly after a timeout. No idempotency key is documented, so a retry may bill again
