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.
