Frequently asked questions
How do I convert a YouTube video to MP3 with the API?+
Send a POST request with the video URL and format 'mp3'. The API downloads the audio, converts it, and returns a direct MP3 link from our CDN — no ffmpeg on your side.
Do I need ffmpeg or yt-dlp?+
No. The API handles extraction and MP3 conversion server-side, so you don't install or maintain ffmpeg, yt-dlp, or any local tooling.
What audio quality do I get?+
The API returns high-quality MP3 audio. You can also request the best original audio stream when you don't specifically need MP3.
Will it get blocked by YouTube's bot detection?+
No — clearing YouTube's bot checks is exactly what the API handles for you, so audio downloads don't fail with 'confirm you're not a bot' or 403 errors.
