## 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).

**Loudly Music API.** Public OpenAPI 3.0 spec with error schemas for 400, 402, 403, 404 and 500. No status page, changelog, rate limits or 429 guidance.

## 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

### Loudly Music API

1. Send `test=true` while wiring up. It returns a dummy song and spends no credits
2. Call `GET /api/ai/genres` first. Genre, BPM range and instrument names must match that list
3. Treat 402 as out of credits and stop, not retry
4. A 403 on Manta routes means the account flag is off, not a bad key
