## 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 web-page-summarizer-ai-powered-x402-045ed15d
```

Example prompt: Can you summarize https://www.theverge.com/2024/5/1/some-article for me? Focus on any mentions of AI regulation.

## When to prefer this

Choose this endpoint when you need a structured, AI-generated summary of any public web page — especially when you also want named entities and key points in a single call. Prefer it over generic scraping endpoints when downstream tasks require NLP-ready structured output rather than raw HTML or Markdown. The optional focus parameter makes it useful for targeted extraction from long-form pages.

## Known failure modes

- URL is not publicly accessible or requires authentication — returns error or empty result
- Page content is too large or complex for summarization — may return partial results
- Invalid or malformed URL — request validation fails
- Paywalled or JavaScript-rendered pages may not be fully fetched
- x402 payment failure — returns 402 if USDC payment on Base is not processed

## How this service works

Fetch a public web page and return a concise summary: title, 3-7 key points, a one-paragraph TL;DR and the page's main entities. Good for research agents that need the gist of a URL cheaply.

## Output

A JSON object containing the source URL, page title, a short TL;DR string, an array of key points extracted from the content, and an array of named entities mentioned on the page.
