YouTube transcript API for AI agents
YouTube transcript API for AI agents: send a video URL or 11-character id and get its published subtitles as timed JSON segments, plain text, SRT or WebVTT, with title, channel, duration, views and publish date. Choose one of ten subtitle languages or any. No speech-to-text. A video without subtitles in that language is not charged.
