How this service works

Pay-per-call structured web data. Failed or empty runs are not charged.

Output

Returns a JSON object with a count of results and an array of items, each containing the video URL, title, video ID, channel ID, channel name, video description, channel username, channel thumbnail, and timed caption segments (plus optionally a joined transcript text string).

Example use cases

Summarize a YouTube lecture

“Get the transcript of this YouTube lecture https://www.youtube.com/watch?v=abc123 in English with the full joined text included — I want to summarize it.”

Extract channel transcripts by date

“Fetch transcripts for up to 50 videos from the YouTube channel @lexfridman that were published between 2024-01-01 and 2024-06-30, in English, stopping after 10 successful transcripts.”

Multilingual caption retrieval

“Pull the transcript for https://youtu.be/xyz789 in Spanish — if Spanish captions aren't available, fall back to whatever language is there.”
