Build a complete karaoke package in one API call — an instrumental backing track, a vocal reference, and time-synced lyrics. All three models run in parallel from a single Task.

​
Create a Task

import requests

API_KEY = "your_api_key"
HEADERS = {"Content-Type": "application/json", "x-api-key": API_KEY}

response = requests.post(
    "https://api.audioshake.ai/tasks",
    headers=HEADERS,
    json={
        "assetId": "your_asset_id",
        "targets": [
            {"model": "instrumental", "formats": ["wav"]},
            {"model": "vocals", "formats": ["wav"]},
            {"model": "alignment", "formats": ["json"]}
        ]
    }
)

task_id = response.json()["id"]
print(f"Task created: {task_id}")
Check Task status to monitor progress and download results, or use webhooks to be notified when each target completes.
