This endpoint doesn't generate the songs instantly, you can use the Fetch endpoint to fetch the result or use webhooks.

The result (posted to the webhook_url or retrieved with the Fetch endpoint) looks like this:

{
    "task_id": "29e983ca-7e86-4017-a9e3-xxxxxxxxx",
    "task_type": "udio-extend",
    "status": "finished",
    "songs": [
      {
        "lyrics": "....",
        "song_id": "ea6813ad-03ce-4a0b-a616-xxxxxxxxx",
        "audio_url": "https://....xxxxxxxxx.mp3",
        "image_url": "https://....xxxxxxxxx.jpeg",
      },
      {
        "lyrics": "...",
        "song_id": "21ad7efc-4954-4ae4-ae2a-xxxxxxxx",
        "audio_url": "https://....xxxxxxxxx.mp3",
        "image_url": "https://....xxxxxxxxx.jpeg",
      }
  ]
}

If the job is not completed, you will get a result like this:

    "task_type": "udio-extend",
