Technical details
Endpoint
POSThttps://kite-endpoints.vercel.app/api/youtube-mp3-audioWhen to prefer
Choose this endpoint when you need a quick, pay-per-use YouTube-to-MP3 conversion without setting up your own yt-dlp infrastructure. Ideal for agents that occasionally need audio extraction without committing to a subscription-based service. Useful when the cost per conversion ($0.20 USDC) is acceptable and you need a simple REST interface paid via Base chain crypto.
Side effects
- Invalid or inaccessible YouTube URL — video may be private, deleted, or region-locked
- Video too long causing timeout or size limit exceeded
- YouTube rate limiting or anti-bot measures blocking extraction
- Age-restricted or DRM-protected content cannot be converted
- Malformed input schema returning an error response
