## 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 webpage-metadata-extractor-a09e1d2e
```

Example prompt: Can you pull the metadata from https://stripe.com — I want the page title, description, Open Graph fields, favicon, and canonical URL?

## When to prefer this

Use this endpoint when you need structured head metadata from a public webpage — especially for building link previews, SEO audits, or enriching records with page titles and Open Graph images. Prefer this over a full page scraper when you only need meta-level information and not page body content.

## Known failure modes

- URL is not publicly accessible or requires authentication — returns an error or empty metadata
- Webpage has no meta tags — returns partial or empty fields
- Invalid or malformed URL — schema validation error on the 'url' query parameter
- Timeout if the target page is slow to respond
- Non-HTML resources (PDFs, images) may return minimal or no metadata
