How this service works
Generate a music track. Poll statusUrl, download at resultUrl. SFW only.
Output
Returns a JSON object with a jobId, initial status (queued), a resultUrl to fetch the final audio once complete, a statusUrl to poll for progress, and an estimated completion time in seconds (typically around 60 seconds, with a poll budget of up to 900 seconds).
Example use cases
Custom song for a birthday celebration
“Write and generate a fun 45-second birthday song with these lyrics: 'Happy birthday to you, may all your dreams come true, wishing you the best day ever!' — make it upbeat and pop-sounding.”
Ambient background music for a home scene
“Create a 60-second calm, atmospheric ambient music track for my evening wind-down routine — something soft and instrumental with no lyrics.”
Custom jingle for a smart home routine
“Generate a short 15-second energetic morning jingle to play when I wake up, something bright and motivating — no lyrics, just an upbeat melody.”
Technical details
Endpoint
POSThttps://api.havenagent.ai/x402/api/v1/musicWhen to prefer
Choose this endpoint when you need to generate original AI music audio — especially short clips (up to 60 seconds) — with optional custom lyrics, in a privacy-focused smart home context. Suitable for home automation agents that want to play personalized music on a Haven speaker or app. Prefer this over text-to-speech endpoints when you want actual musical output, not spoken word.

- Payment of 0.1 USDC not completed via x402 results in 402 Payment Required
- Job may timeout if polling exceeds 900 seconds
