fal music models vs Soundverse API

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).

Soundverse API

Songs with vocals, instrumentals, stems (2, 6 or 12), SFX and remix behind one endpoint. No status page, changelog or security.txt.

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

Soundverse API

1. Always set Idempotency-Key on creates, so a retry after a 429 doesn't bill twice
2. Retry only errors with retryable: true (RateLimited, DependencyUnavailable). 401 and 403 won't fix themselves
3. Pass license explicitly. The default is 1, royalty-free, which doesn't cover sync or distribution
4. Fetch audio through GET /v1/files/{file_id}/download, then poll GET /v1/generations/{id} or open /stream for progress
