Verdicts

ElevenLabs Music API

Vocals and lyrics in several languages, or forced instrumental, with length set from 3 to 600 seconds. Music API is disabled on the Free plan and pay-as-you-go needs a card.

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

ElevenLabs Music API

  1. Strip artist and song names from user prompts before calling, or the request breaks the Music Terms
  2. Pin model_id. The API default is still music_v1
  3. Set music_length_ms and force_instrumental: true for background beds. Billing is by minute of audio
  4. On 429, retry system_busy with exponential backoff, but treat too_many_concurrent_requests as a plan limit and queue
  5. Don't plan on the MCP server for music. Its documented tools cover agents and speech

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
