How this service works
Summarizes a YouTube video from its URL or ID: transcript, TLDR, and named entities in one call. Composite: one call runs youtube-transcript + summarize-text + extract-entities. Pulls the YouTube transcript, then summary and named entity extraction (people, orgs, locations, dates) run in parallel. Returns transcript excerpt, summary, entities, and per-component telemetry. Use it as a video digest or closed-caption summarizer.
Output
Returns a transcript excerpt from the video, a concise TLDR summary, and a structured list of named entities classified by type (people, organizations, locations, dates). Also includes per-component telemetry showing latency and status for each of the three underlying operations (transcript fetch, summarization, entity extraction).
Example use cases
Research briefing from a conference talk
“I don't have time to watch this 45-minute keynote — https://www.youtube.com/watch?v=abc123xyz — can you pull the transcript excerpt, give me a TLDR, and list every company and speaker name that comes up?”
Journalist entity check on a news video
“Can you analyze this YouTube news segment at https://www.youtube.com/watch?v=news456vid and extract all the people, organizations, and locations mentioned? I need the summary too so I can cross-reference for my article.”
Student lecture notes assistant
“I need quick notes from this university lecture video — https://www.youtube.com/watch?v=lecture789 — give me the TLDR and any key dates or people referenced in the transcript.”

Endpoint
POSThttps://x402.agentutility.ai/youtube-brief?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a one-call composite result combining transcript, summary, and entity extraction from a YouTube video. It is ideal when you want to avoid chaining three separate API calls and need the named-entity layer (people, orgs, locations, dates) alongside the TLDR — distinguishing it from plain summarization endpoints. Best suited for research, journalism, content review, or any agent workflow that needs structured intelligence extracted from video content.
Side effects
- Video is private or age-restricted — transcript fetch fails with an access error
- Video has no captions or auto-generated transcript disabled — returns empty transcript
- Invalid or malformed YouTube URL/ID — returns a validation error
- Video is too long and transcript exceeds token limits — may return truncated summary
- Upstream YouTube transcript service temporarily unavailable — component telemetry will show failure for that step
