Workflow

Genre Remix

Re-style an existing song into a different genre or mood while keeping its original lyrics. Soundverse transcribes the song first and passes the lyrics to the remix.

Dedicated route only

This workflow uses POST /v1/genre-remixes. It runs a fixed multi-step pipeline; there is no generic tool_id for it.

Quickstart

POST/v1/genre-remixesgenre remix

curl -X POST https://apiv2.soundverse.ai/v1/genre-remixes \
  -H "Authorization: Bearer sksoundverse_..." \
  -H "Content-Type: application/json" \
  -H "Idempotency-Key: genre-remix-001" \
  -d '{
  "song_file_id": "018f0000-0000-7000-8000-000000000002",
  "remix_style": "lofi hip-hop",
  "license": "royalty_free"
}'

The song_file_id must be an active uploaded audio file owned by the authenticated enterprise account.

Getting a song_file_id

Upload the file first via POST /v1/files — either {"source_url": "..."} if you already host it, or a multipart/form-data file part to upload bytes directly. Both return a file_id owned by your account, ready to pass here.

Request fields

Field	Type	Required	Default	Description
song_file_id	uuid	Yes	—	ID of the vocal song to remix, an audio file owned by the authenticated enterprise account (upload it first via POST /v1/files). The original lyrics are transcribed and preserved. Maximum 60 MiB.
remix_style	string	Yes	—	Target style or genre (e.g. 'chill RnB', 'lofi hip-hop', 'orchestral cinematic').
license	license tier	No	"royalty_free"	License tier to price and attach to every step of the pipeline.

How it works

Each request runs 2 steps in order:

Transcribing the original song’s lyrics.
Generating the remix in the requested style with the original lyrics.

Progress streams over GET /v1/generations/{task_id}/stream as each step starts and finishes.

Notes

The original lyrics are transcribed first and passed to the remix, so the new version keeps your song’s words.

Results and playback

Poll GET /v1/generations/{task_id} until the task is completed. The finished result is added to the authenticated account’s Soundverse Library. Enterprise API outputs are hidden from public/profile surfaces by default.

For API-only download, resolve the output’s file_id with GET /v1/files/{file_id}/url and use the returned short-lived signed URL.

Pricing

This workflow is priced pass-through: you are billed for each step the pipeline runs, at that step’s enterprise rate, in the license tier you requested. The pipeline itself adds no separate fee, and your billing ledger shows one entry per step. The steps that carry the cost are:

Lyric transcription
Remix generation

There is no fixed per-request price; the total depends on the input and on which optional steps run.
