Request Parameters

It is recommended to describe the song's theme, style, and mood to get better-fitting lyrics

Response

code integer

Response status code, 200 on success

data array

Array of returned data

status string

Task status, submitted upon initial submission

task_id string

Unique task identifier, used to query task status and results

Use Cases

Scenario 1: Generate lyrics by theme

{
  "model": "flowmusic",
  "prompt": "A rock song about perseverance"
}

Scenario 2: Fill generated lyrics into a song

First generate lyrics; once done, take the title and lyrics from result.lyrics[0] and fill them into the Generate Music endpoint:

{
  "model": "flowmusic",
  "title": "Perseverance",
  "lyrics": "[Verse 1]\nEven the longest night turns to dawn\n...",
  "sound_prompt": "energetic rock with electric guitar"
}

Note

Query Task Results

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