    "description": "\nThis is the LALAL.AI API.\n\nTo authenticate, provide your license key in the `X-License-Key` header of each request.\n\nTypical usage example:\n1) Upload a file using the '/upload/' endpoint to get a 'source_id'.\n2) Start a splitting task using the '/split/' endpoint with the obtained 'source_id' and desired presets.\n3) Check the status of your task using the '/check/' endpoint with the returned 'task_id'.\n4) Once the task is complete, download the processed files using urls from the '/check/' response.\n5) (If needed), you can delete the source file and all its resulting tracks from our servers, using the '/delete/' endpoint with the 'source_id'.\n\nNotes:\n\nYou can use the same source_id for concurrent splitting tasks.\n\nYou can check multiple task IDs in a single '/check/' request by providing a list of 'task_ids'.\n\n",
