task_id and then poll GET /v1/music/tasks/{task_id} every 3–5 seconds until status becomes completed or failed (while generation is in progress, status may be pending or processing, and progress is an integer from 0 to 100 and is not guaranteed to change at fixed intervals). Once completed, the result contains the separated track URL. In case of failure, data.error.message provides the reason, and the deducted amount will be automatically refunded.Response
