## 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 agenttools-url-metadata-extractor-99ef4134
```

Example prompt: Can you fetch the title, meta description, OG image, and favicon for https://example.com so I can build a link preview card?

## When to prefer this

Use this endpoint when an agent needs to generate a link preview (title, description, image, favicon) for a given URL without running client-side JavaScript, or when classifying/enriching a URL with its structured metadata. Prefer this over raw HTML fetching when only head-level metadata is needed, as it returns pre-parsed, structured fields rather than raw HTML.

## Known failure modes

- URL resolves to a private/internal IP address — blocked by SSRF guard
- Response body exceeds 1MB cap — truncated or error returned
- Page takes longer than 10 seconds to respond — timeout error
- Malformed or non-HTTP URL provided — validation error
- Target page returns non-200 status code — upstream error reported
- Page has no OG/meta tags — fields returned as null or empty

## How this service works

Fetch a URL server-side and extract its title, meta description, Open Graph and Twitter card tags, canonical URL and favicon — the data agents need to preview or classify a link. SSRF-guarded: private networks are blocked, 10s timeout, 1MB cap. Use this when an agent needs to title, description, OG image and favicon of any page.

## Output

Returns the page title, meta description, Open Graph properties (og:title, og:description, og:image, og:url), Twitter card tags, canonical URL, and favicon URL extracted from the target page's HTML.
