No status page, changelog or security.txt.\n\n## Before you call either\n\n### Loudly Music API\n\n1. Send `test=true` while wiring up. It returns a dummy song and spends no credits\n2. Call `GET /api/ai/genres` first. Genre, BPM range and instrument names must match that list\n3. Treat 402 as out of credits and stop, not retry\n4. A 403 on Manta routes means the account flag is off, not a bad key\n\n### Soundverse API\n\n1. Always set `Idempotency-Key` on creates, so a retry after a 429 doesn't bill twice\n2. Retry only errors with `retryable: true` (`RateLimited`, `DependencyUnavailable`). 401 and 403 won't fix themselves\n3. Pass `license` explicitly. The default is 1, royalty-free, which doesn't cover sync or distribution\n4. Fetch audio through `GET /v1/files/{file_id}/download`, then poll `GET /v1/generations/{id}` or open `/stream` for progress\n\n## Other comparisons with Loudly Music API or Soundverse API\n\n- [Beatoven.ai API vs Loudly Music API](https://www.anchorterminal.com/compare/beatoven-vs-loudly.md)\n- [Beatoven.ai API vs Soundverse API](https://www.anchorterminal.com/compare/beatoven-vs-soundverse.md)\n- [ElevenLabs Music API vs Loudly Music API](https://www.anchorterminal.com/compare/elevenlabs-music-vs-loudly.md)\n- [ElevenLabs Music API vs Soundverse API](https://www.anchorterminal.com/compare/elevenlabs-music-vs-soundverse.md)\n- [fal music models vs Loudly Music API](https://www.anchorterminal.com/compare/fal-music-vs-loudly.md)\n- [fal music models vs Soundverse API](https://www.anchorterminal.com/compare/fal-music-vs-soundverse.md)\n- [Google Lyria vs Loudly Music API](https://www.anchorterminal.com/compare/google-lyria-vs-loudly.md)\n- [Google Lyria vs Soundverse API](https://www.anchorterminal.com/compare/google-lyria-vs-soundverse.md)\n- [Loudly Music API vs Mubert API](https://www.anchorterminal.com/compare/loudly-vs-mubert.md)\n- [Loudly Music API vs MusicGen on Replicate](https://www.anchorterminal.com/compare/loudly-vs-replicate-musicgen.md)\n- [Loudly Music API vs SOUNDRAW API](https://www.anchorterminal.com/compare/loudly-vs-soundraw.md)\n- [Loudly Music API vs Stable Audio API](https://www.anchorterminal.com/compare/loudly-vs-stable-audio.md)\n- [Mubert API vs Soundverse API](https://www.anchorterminal.com/compare/mubert-vs-soundverse.md)\n- [MusicGen on Replicate vs Soundverse API](https://www.anchorterminal.com/compare/replicate-musicgen-vs-soundverse.md)\n- [SOUNDRAW API vs Soundverse API](https://www.anchorterminal.com/compare/soundraw-vs-soundverse.md)\n- [Soundverse API vs Stable Audio API](https://www.anchorterminal.com/compare/soundverse-vs-stable-audio.md)\n",
