## Verdicts

**fal music models.** Lyria, ElevenLabs, MiniMax, Stable Audio, Beatoven and open-weights models behind one queue API. Billing units differ per model (per track, per second, per minute rounded up).

**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

### fal music models

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

### 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
