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.

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

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

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
