## 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 ai-web-page-summarizer-dfd852ef
```

## When to prefer this

Use this endpoint when you need a quick AI-generated summary of any publicly accessible webpage, especially when you want to avoid reading a full article or page yourself. Prefer this over general-purpose scrapers when you specifically need condensed, natural-language summaries rather than raw HTML or structured data extraction.

## Known failure modes

- URL is unreachable or returns non-200 status — fetch failure error
- URL points to a non-text resource (PDF, image, video) that cannot be parsed
- maxLength parameter is invalid or out of acceptable range
- URL is missing or malformed in the query params
- Target page is paywalled or requires authentication — content unavailable
- Rate limiting or payment verification failure for x402 protocol

## How this service works
