Technical details
Endpoint
POSThttps://gateway.d402.xyz/v1/youtube/transcriptWhen to prefer
Use this endpoint when you need the spoken or captioned text of a YouTube video, especially with timestamps, and want validation evidence (transcript hash, receipt) confirming what was extracted. Prefer this over screen-scraping solutions when you need structured segment data with start/end times, or when you need proof of the extracted content.
Side effects
- Video has no transcript or captions available — returns error status
- Private or age-restricted video URL — workers cannot access the page
- Invalid or malformed YouTube URL — request rejected with validation error
- Requested language code not available on the video — may fall back or error
- Timeout exceeded before transcript could be fetched — returns error status
- Video has been deleted or made unavailable — workers return error
