Suno alternative with an API: what Sume's Music Router does

If you searched for a Suno alternative with an API, here is what Sume offers, stated on its own terms: a Music Router at POST /v1/music-router/generate that turns a text prompt (and an optional image) into a track through Lyria 3.5 or Lyria 3 Pro, returned as a hosted audio file from a job. This post makes no comparison with any other service; use it to check the fit against your needs.

Every Sume fact is from the Music Router and Music 1.0 docs and the pricing page, read 2026-09-29.

What can the API do?

What does a call look like?

curl -X POST https://api.sume.com/v1/music-router/generate \
  -H "Authorization: Bearer $SUME_API_KEY" \
  -H "Content-Type: application/json" \
  -H "Idempotency-Key: alt-001" \
  -d '{
    "prompt": "Punchy funk-pop, 108 BPM, B-flat major. Slap bass, brass stabs. A 1-minute track. Instrumental, no vocals."
  }'

How do I get the file?

Poll GET /v1/jobs/{id}/status until completed, then read GET /v1/jobs/{id}/result for the audio in result.artifacts[], typically audio/mpeg on media.sume.com. Use Sume media URLs from the result; raw provider URLs are not public outputs.

What does it cost, and what about rights?

Every Music Router model charges the fixed music price per generation, shown on API pricing, plus the default agent fee. For rights, read the Sume Terms of Service yourself; the docs pages above do not state a licence for generated music.
