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 ## Other comparisons with Beatoven.ai API or Loudly Music API - [Beatoven.ai API vs ElevenLabs Music API](https://www.anchorterminal.com/compare/beatoven-vs-elevenlabs-music.md) - [Beatoven.ai API vs fal music models](https://www.anchorterminal.com/compare/beatoven-vs-fal-music.md) - [Beatoven.ai API vs Google Lyria](https://www.anchorterminal.com/compare/beatoven-vs-google-lyria.md) - [Beatoven.ai API vs Mubert API](https://www.anchorterminal.com/compare/beatoven-vs-mubert.md) - [Beatoven.ai API vs MusicGen on Replicate](https://www.anchorterminal.com/compare/beatoven-vs-replicate-musicgen.md) - [Beatoven.ai API vs SOUNDRAW API](https://www.anchorterminal.com/compare/beatoven-vs-soundraw.md) - [Beatoven.ai API vs Soundverse API](https://www.anchorterminal.com/compare/beatoven-vs-soundverse.md) - [Beatoven.ai API vs Stable Audio API](https://www.anchorterminal.com/compare/beatoven-vs-stable-audio.md) - [ElevenLabs Music API vs Loudly Music API](https://www.anchorterminal.com/compare/elevenlabs-music-vs-loudly.md) - [fal music models vs Loudly Music API](https://www.anchorterminal.com/compare/fal-music-vs-loudly.md) - [Google Lyria vs Loudly Music API](https://www.anchorterminal.com/compare/google-lyria-vs-loudly.md) - [Loudly Music API vs Mubert API](https://www.anchorterminal.com/compare/loudly-vs-mubert.md) - [Loudly Music API vs MusicGen on Replicate](https://www.anchorterminal.com/compare/loudly-vs-replicate-musicgen.md) - [Loudly Music API vs SOUNDRAW API](https://www.anchorterminal.com/compare/loudly-vs-soundraw.md) - [Loudly Music API vs Soundverse API](https://www.anchorterminal.com/compare/loudly-vs-soundverse.md) - [Loudly Music API vs Stable Audio API](https://www.anchorterminal.com/compare/loudly-vs-stable-audio.md)
