Use Cases

Scenario 1: Import external audio in exchange for a clip_id

{
  "model": "flowmusic",
  "audio_url": "https://example.com/audio.mp3"
}

Once completed, take the imported clip_id from result.music[0].clip_id; it can then be used for Extend / Replace / Cover / Stems.

Query Task ResultsAudio upload is an asynchronous task; a task_id is returned after submission. Use the Get Task Status endpoint to query generation progress and results.
