POST
Source Audio Reference: No additional IDs are needed for tracks based on existing songs. Just pass task_id (the task ID from the previous run of this task) + audio_index (which result track in the data.result.music[] list, 1-based, default is 1).
This endpoint has no version dimension: do not pass version — if passed, it is discarded and does not affect billing.

Body

string
default:"suno"
Audio model. Currently pass suno (defaults to suno if omitted).
string
required
Our task_id of the job that produced the source track. If missing or the source cannot be resolved, a 400 is returned at submission time.
integer
default:"1"
Selects a track from the source task’s data.result.music[] array (1-based; default 1).
string
required
Persona name. If missing, returns 400 immediately.
string
Description.
string
Style.
number
Start point of the voice clip in seconds, must be greater than or equal to 0. Suggested paired with vocal_end_s.
number
End point of the voice clip in seconds, must be greater than the start point and not exceed the known source duration.
Read result.persona_id after completion. The Persona ID is different from the custom model ID and cannot be used as an API value for model; a new process does not require creating Vox beforehand.
Get Result: This is an asynchronous task. After submission, you will receive task_id and then poll GET /v1/music/tasks/{task_id} every 3–5 seconds until status becomes completed or failed (usually 30–120 seconds; 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 persona information. In case of failure, data.error.message provides the reason and the deducted amount will be automatically refunded.
