AI Music Generation APIs

This section covers supported APIs and durable integration patterns for programmatic music generation. Provider contracts change quickly: verify endpoints, fields, model identifiers, limits, pricing, and terms in current first-party documentation before deployment.

:::info Freshness rule

Provider pages explain integration boundaries and link to the live contract. They do not treat undocumented browser endpoints or copied wrappers as supported APIs. See Reliability and Sourcing for the evidence standard.

Common Concepts

Asynchronous Generation

Long-running music generation commonly uses asynchronous jobs. A provider may support polling, webhooks, streaming, synchronous previews, or a combination; follow its documented contract.

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

Rate Limits

Hosted services commonly enforce request, concurrency, duration, or account 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
