POST
Referencing the source track: this endpoint does not use task_id + audio_index; you must directly provide a publicly accessible audio_url (the upstream extracts the voice from it). If missing, returns 400 audio_url cannot be empty.
This endpoint has no version dimension: do not pass version — if passed, it is discarded and does not affect billing.

Getting the result: This endpoint is an async task. After submitting you get a task_id; poll GET /v1/music/tasks/{task_id} at 3–5s intervals until status is completed or failed (typically takes 30–120s; while generating, status is pending and progress goes queued 10 → ready 50 → done 100). The result contains the created voice information. On failure data.error.message gives the reason and the pre-deducted quota is automatically refunded.
