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.

MusicGPT API

A public OpenAPI 3.1 file with 27 operations, llms.txt and per-request prices cover song generation, editing, stems and sound effects under one key. No status page, SLA, security.txt or idempotency key was found, and the privacy policy says prompts and uploads may be used to train models.

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

MusicGPT API

  1. Send the key as the raw Authorization header value. The docs show no Bearer prefix
  2. Budget two songs for each music request. POST /v2/MusicAI returns two versions and the price is per song
  3. Save task_id and poll GET /v1/byId with conversionType, or set webhook_url. Music AI V2 sends up to seven webhooks a request
  4. Pass model explicitly. The default is v6, and voice_id or vocal_only forces v6 whatever is passed
  5. Do not retry a create blindly after a timeout. No idempotency key is documented, so a retry may bill again
