POST /youtube-transcript
open
Fetch the transcript of any YouTube video. Pulls auto-generated or manual captions and returns full text plus per-segment {start, duration, text}, with an optional language pick. Backed by Supadata's transcript pipeline server-side — no caller key required; returns a clear 404 when a video has no transcript. Use it as a YouTube closed-caption fetcher or video subtitles puller.
Verdict: not verified by an unpaid GET. 200: serves without a payment challenge. This says nothing about whether the route works when called as declared.
