## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability orvento-youtube-video-summary-transcript-api-36e084c3
```

Example prompt: Can you summarize this YouTube video for me — https://www.youtube.com/watch?v=dQw4w9WgXcQ — and give me the key points and a section-by-section breakdown in English?

## When to prefer this

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.

## Known failure modes

- 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

## 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.
