Technical details
Endpoint
POSThttps://agdata.shveik.dev/v1/mpp/youtube-transcript?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to extract the spoken content from a YouTube video as structured or plain-text data, especially when you want timing metadata (SRT/VTT), multi-language support, or rich video metadata alongside the transcript. Prefer this over generic web unblockers when the target is specifically a YouTube transcript, as it handles YouTube's caption API natively and returns structured segment data.
Side effects
- Video has no captions or subtitles available — transcript array will be empty
- Requested language not available for the video — may fall back or return error
- Invalid or inaccessible video URL — returns error response
- Video is private or age-restricted — may be blocked
- Truncation of very long transcripts indicated by truncated:true flag
