Verdicts

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.

SOUNDRAW API

Trained only on in-house compositions, per SOUNDRAW. No public API docs, OpenAPI spec, SDK or changelog.

Before you call either

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

SOUNDRAW API

  1. Needs a contract and token before any call. There's nothing to probe anonymously
  2. Save generated files within 72 hours. The links expire and songs are deleted
  3. Don't let end users resell raw tracks. The licence restricts it
