Understanding the Extract Audio as MP3 Endpoint

The endpoint for extracting audio from a video is straightforward and easy to use. The POST request to the '/api/extract_audio_mp3' path enables you to specify the video URL and the desired audio bitrate.

This method downloads the video and returns the audio track in MP3 format, making it perfect for applications that need audio files extracted promptly.

  • Endpoint: /api/extract_audio_mp3
  • Method: POST
  • Content Type: application/json or form data
