Poll this endpoint to check the status of your music generation task.
If the create response included poll_url, prefer calling that exact URL for polling. /v1/tasks/{id} is the canonical fixed status endpoint for music jobs, and id / task_id should be treated as the same async task identity.If the task no longer exists or is no longer available in the public task record, TokenLab returns async_task_not_found with the message Task not found or no longer available.

​
