Workflow Example

Most audio processing operations are asynchronous. Here's a typical workflow:

1. Start a conversion (e.g., generate_music)

   • Returns: task_id and conversion_id

2. Check status using get_conversion_by_id

   • Pass the task_id or conversion_id
   • Status values: PENDING, PROCESSING, COMPLETED, FAILED

3. Get results when status is COMPLETED

   • The response includes audio_url with the processed audio

Example:

// Step 1: Generate music
{
  "tool": "generate_music",
  "arguments": {
    "prompt": "A relaxing piano melody"
  }
}
// Returns: { task_id: "abc-123", conversion_id: "def-456", eta: 120 }

// Step 2: Check status (wait for ETA or use webhook)
{
  "tool": "get_conversion_by_id",
  "arguments": {
    "conversionType": "MUSIC_AI",
    "task_id": "abc-123"
  }
}
// Returns: { status: "COMPLETED", audio_url: "https://..." }

Webhook Support

Most conversion tools support webhooks for async notifications. Set the webhook_url parameter to receive a callback when processing completes:

{
  "prompt": "Epic orchestral music",
  "webhook_url": "https://your-server.com/musicgpt-webhook"
}

The webhook will receive a POST request with the conversion results.
