Example request

Set OMNAPI_KEY on your server and create REQUEST_ID once for this logical request. Reuse that ID on transport retries. A new generation can incur a charge; review current pricing first.

curl --fail-with-body --max-time 60 -X POST "https://api.omnapi.com/api/v1/producer/generate/music/compose" \
  -H "x-api-key: $OMNAPI_KEY" \
  -H "Idempotency-Key: $REQUEST_ID" \
  -H "Content-Type: application/json" \
  --data '{
  "soundPrompt": "Warm instrumental indie pop, jangly guitars and brushed drums",
  "instrumental": true,
  "length": 60
}'

soundPrompt is required and allows up to 500 characters. length accepts 1–600 seconds. Add approved lyrics when you want a vocal song instead of this instrumental example.

FAQ

What kinds of products use this page?

Use this endpoint when your application needs to turn a musical brief into audio. Save the task ID, handle terminal errors, and review the result before publishing.

Why is async workflow emphasized?

Longer-running media jobs are easier to manage reliably with queueing, status tracking, and result retrieval patterns.
