## 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 pagewatch-web-page-data-extractor-40bb0474
```

Example prompt: Can you extract the price from this product page — https://www.example.com/product/widget — using the price extraction mode?

## When to prefer this

Choose this endpoint when you need to extract specific structured data from a known public static HTML page — especially prices, tables, event lists, or links — and you can provide a CSS selector or JSONPath to target the data. It is ideal for lightweight, single-page extraction tasks where the target page does not require JavaScript rendering or authentication. Prefer alternatives if the target page is JavaScript-heavy (SPA), requires login, or you need to crawl multiple pages.

## Known failure modes

- URL is not publicly accessible or requires authentication — returns error
- Page uses JavaScript rendering — static HTML only, dynamic content will not be present
- CSS selector matches nothing — returns empty or null data
- Invalid or unsupported URL (non-public DNS, non-standard ports) — rejected
- JSONPath expression matches nothing in the JSON payload — empty result
- Table index out of bounds — no data returned
- Malformed CSS selector or JSONPath — validation error
- Page returns non-200 HTTP status — fetch error

## How this service works

Extract prices, lists, tables and events from public web pages and get notified when they change. RSS, ICS, signed webhooks, MCP. Static HTML only.

## Output

A JSON object containing the extracted data under a 'data' field (type depends on mode — scalar, array, or object), plus metadata including the extraction mode used, number of matches, whether results were truncated, the final resolved URL, and the timestamp when the page was fetched.
