Technical details
Endpoint
POSThttps://x402vid.com/tools/transcript_markdown?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need the raw spoken transcript of a YouTube video as structured Markdown text, particularly when you want a ready-to-use document with a title and filename. Prefer this over general-purpose transcription services when your input is specifically a YouTube URL or video ID, and you want a pay-per-call model with no subscription overhead.
Side effects
- Video URL or ID is invalid or malformed — returns an error indicating the video could not be found
- Video has no captions or transcript available (e.g. auto-captions disabled, non-speech content) — may return empty Markdown or an error
- Video is private or age-restricted and cannot be accessed — returns an access error
- Network or upstream service timeout for very long videos — may return a partial transcript or timeout error
- Payment not completed (x402 protocol failure) — request rejected before processing
