## 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 agentreader-web-page-metadata-extractor-b46dd5ed
```

Example prompt: Can you pull the metadata from https://www.bbc.com/news/technology — I want to see the page title, description, Open Graph tags, and any JSON-LD types on that page.

## When to prefer this

Use this endpoint when you need lightweight, fast metadata extraction from a web page without full content scraping — ideal for link previews, SEO audits, social tag inspection, and JSON-LD type detection. Prefer it over full-page scrapers when you only need header-level metadata rather than body text.

## Known failure modes

- URL is unreachable or returns a non-200 status — endpoint may return an error or empty metadata
- Page uses JavaScript rendering and metadata is injected client-side — static fetch may miss dynamically loaded tags
- URL parameter missing or malformed — returns 400 bad request
- Target page blocks bots/crawlers — may return empty or partial metadata
- Very large pages may time out on the Cloudflare Worker

## How this service works

Extract structured metadata from any web page: title, description, canonical URL, Open Graph and Twitter card tags, favicons, JSON-LD types, language and headings. Useful for link previews, content classification and SEO analysis.

## Output

A structured JSON object containing the page's title, meta description, canonical URL, Open Graph properties (og:title, og:description, og:image, etc.), Twitter card tags, favicon URLs, JSON-LD @type values found on the page, the declared language, and an array of heading elements (h1-h6).
