How it works:

1. Send a POST request to the API with the videoId of the YouTube video.
2. The API will return the MP3 download link ready for use.

Accepted Parameters:

• videoId: The unique ID of the YouTube video (e.g., for https://www.youtube.com/watch?v=dQw4w9WgXcQ, the videoId would be dQw4w9WgXcQ).

Response Format:
The response includes the request status and the MP3 download link.

Perfect for developers who want to integrate video-to-MP3 conversion functionality into their applications or services.
