    1. **Step 1**: Submit task to Suno API → Get `taskId` from response
    2. **Step 2**: Suno processes audio (async)
    3. **Step 3**: Suno sends callback to: `https://1hit.no/wav/cb.php`
    4. **Step 4**: You can view callbacks at: `https://1hit.no/wav/view.php`
    5. **Step 5**: OR use Poll button to check status via `/api/v1/record-info` endpoint

    ### Polling Endpoint:
    ```javascript
    fetch('https://api.sunoapi.org/api/v1/wav/record-info', {

        'Authorization': 'Bearer YOUR_TOKEN'
