How this service works
YouTube video summaries and transcripts for AI agents. Pay per call in USDC over x402 via Circle Gateway. No signup, no API key.
Output
A Markdown-formatted response with three sections: a TL;DR (one-paragraph overview), a bulleted Key Points list, and a Section-by-Section breakdown with timestamps (e.g. '00:00 — Intro: …'). Returned as JSON with a 'summary' string field.
Example use cases
Research digest from lecture video
“Summarize this two-hour MIT lecture on machine learning for me — https://www.youtube.com/watch?v=aircAruvnKk — I want the TL;DR, the main takeaways, and what's covered minute by minute, in English.”
Quick news video briefing
“I don't have time to watch this 30-minute news analysis video. Can you pull out the key points and a section breakdown from https://www.youtube.com/watch?v=5qap5aO4i9A?”
Foreign language video in English
“This YouTube video is in German — https://www.youtube.com/watch?v=example123 — can you summarize it in English so I know what it's about?”
Technical details
Endpoint
GEThttps://orvento.link/v1/summary?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an agent needs to quickly extract structured information from a YouTube video without watching it — especially for research, briefing, or content digestion workflows. It is ideal for no-signup, pay-per-call scenarios where provisioning API keys is undesirable. Prefer it over generic LLM-based summarization when the input is a YouTube URL and you need timestamped section breakdowns alongside key points.
Side effects
- Invalid or private YouTube URL returns an error — video must be publicly accessible
- Unsupported language code returns an error or falls back to English
- Video with no captions/transcript available may fail or produce a lower-quality summary
- Network timeout if the video is very long and transcript fetching is slow
- Payment not processed (x402 failure) results in 402 response before summary is returned
