AI Music Generation APIs

This section covers the public and unofficial APIs available for programmatic access to AI music generation platforms. Whether you're building a creative tool, automating a production pipeline, or experimenting with generative audio, understanding these APIs is essential.

Common Concepts​

Asynchronous Generation​

All AI music generation APIs operate asynchronously. You submit a job and poll for results — generation typically takes 10–60 seconds depending on track length and server load.

POST /generate   →  202 Accepted  { job_id }
GET  /status/:id →  200 { status: "processing" | "complete" | "failed" }

Rate Limits​

Most services enforce per-minute and per-day quotas. Design your integration to:

  • Respect Retry-After headers
  • Implement exponential back-off
  • Cache completed assets by job_id to avoid re-generation

Audio Formats​

APIs typically return one of:

  • MP3 — universal, streaming-friendly
  • WAV — lossless, preferred for further processing
  • M4A / AAC — common on mobile-first services
