Music API is disabled on the Free plan and pay-as-you-go needs a card.\n\n**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.\n\n## Before you call either\n\n### ElevenLabs Music API\n\n1. Strip artist and song names from user prompts before calling, or the request breaks the Music Terms\n2. Pin `model_id`. The API default is still `music_v1`\n3. Set `music_length_ms` and `force_instrumental: true` for background beds. Billing is by minute of audio\n4. On 429, retry `system_busy` with exponential backoff, but treat `too_many_concurrent_requests` as a plan limit and queue\n5. Don't plan on the MCP server for music. Its documented tools cover agents and speech\n\n### Stable Audio API\n\n1. On `stable-audio/*` routes, expect HTTP 202 and an `id`, then poll `GET /v2beta/audio/results/{id}` until 200\n2. Send `accept: audio/*` for raw bytes, not base64 JSON\n3. Set `duration`. It defaults to 190 seconds on 3.0\n4. Wait 60 seconds after a 429 before the next call\n5. Use the `stable-audio-2` routes for inpainting. 3.0 has no inpaint route\n\n## Other comparisons with ElevenLabs Music API or Stable Audio API\n\n- [Beatoven.ai API vs ElevenLabs Music API](https://www.anchorterminal.com/compare/beatoven-vs-elevenlabs-music.md)\n- [Beatoven.ai API vs Stable Audio API](https://www.anchorterminal.com/compare/beatoven-vs-stable-audio.md)\n- [ElevenLabs Music API vs fal music models](https://www.anchorterminal.com/compare/elevenlabs-music-vs-fal-music.md)\n- [ElevenLabs Music API vs Google Lyria](https://www.anchorterminal.com/compare/elevenlabs-music-vs-google-lyria.md)\n- [ElevenLabs Music API vs Loudly Music API](https://www.anchorterminal.com/compare/elevenlabs-music-vs-loudly.md)\n- [ElevenLabs Music API vs Mubert API](https://www.anchorterminal.com/compare/elevenlabs-music-vs-mubert.md)\n- [ElevenLabs Music API vs MusicGen on Replicate](https://www.anchorterminal.com/compare/elevenlabs-music-vs-replicate-musicgen.md)\n- [ElevenLabs Music API vs SOUNDRAW API](https://www.anchorterminal.com/compare/elevenlabs-music-vs-soundraw.md)\n- [ElevenLabs Music API vs Soundverse API](https://www.anchorterminal.com/compare/elevenlabs-music-vs-soundverse.md)\n- [fal music models vs Stable Audio API](https://www.anchorterminal.com/compare/fal-music-vs-stable-audio.md)\n- [Google Lyria vs Stable Audio API](https://www.anchorterminal.com/compare/google-lyria-vs-stable-audio.md)\n- [Loudly Music API vs Stable Audio API](https://www.anchorterminal.com/compare/loudly-vs-stable-audio.md)\n- [Mubert API vs Stable Audio API](https://www.anchorterminal.com/compare/mubert-vs-stable-audio.md)\n- [MusicGen on Replicate vs Stable Audio API](https://www.anchorterminal.com/compare/replicate-musicgen-vs-stable-audio.md)\n- [SOUNDRAW API vs Stable Audio API](https://www.anchorterminal.com/compare/soundraw-vs-stable-audio.md)\n- [Soundverse API vs Stable Audio API](https://www.anchorterminal.com/compare/soundverse-vs-stable-audio.md)\n",
