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.

Stable Audio API

Pay-as-you-go credits, $0.26 a 3.0 generation and $0.20 on 2.5, failures free. Stable Audio 3.0 is async only, with polling and no webhook, and inpaint stays on 2 and 2.5.

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

Stable Audio API

  1. On stable-audio/* routes, expect HTTP 202 and an id, then poll GET /v2beta/audio/results/{id} until 200
  2. Send accept: audio/* for raw bytes, not base64 JSON
  3. Set duration. It defaults to 190 seconds on 3.0
  4. Wait 60 seconds after a 429 before the next call
  5. Use the stable-audio-2 routes for inpainting. 3.0 has no inpaint route
