  title: Suno API (sunoapi.org) Lyrics API
  description: Third-party Suno API gateway (sunoapi.org) for AI music, lyrics, and audio generation. Suno itself does not publish a sanctioned developer API as of May 2026; this OpenAPI describes the public-facing endpoints documented at https://docs.sunoapi.org. Endpoints are asynchronous and rely on a callBackUrl for completion notifications, with task status retrievable via record-info endpoints.
