  description: '

    This is the LALAL.AI API.


    To authenticate, provide your license key in the `X-License-Key` header of each request.


    Typical usage example:

    1) Upload a file using the ''/upload/'' endpoint to get a ''source_id''.

    2) Start a splitting task using the ''/split/'' endpoint with the obtained ''source_id'' and desired presets.

    3) Check the status of your task using the ''/check/'' endpoint with the returned ''task_id''.

    4) Once the task is complete, download the processed files using urls from the ''/check/'' response.

    5) (If needed), you can delete the source file and all its resulting tracks from our servers, using the ''/delete/'' endpoint with the ''source_id''.


    Notes:


    You can use the same source_id for concurrent splitting tasks.


    You can check multiple task IDs in a single ''/check/'' request by providing a list of ''task_ids''.
