## How to call it through Zero

```sh
zero fetch --capability agent-tools-web-meta-extractor-ca5db57f
```

Example prompt: Can you fetch the link preview metadata for https://openai.com — I need the title, description, og:image, site name, and the final URL after any redirects?

## When to prefer this

Use this endpoint when you need structured link preview or unfurl data from a URL — including title, description, og:image, site name, favicon, and the resolved final URL after redirects. Prefer it over full page scrapers when you only need metadata (not page content) and want a fast, lightweight response. It is ideal for building link cards, enriching shared URLs, auditing Open Graph tags, or validating what a link will look like when shared on social or messaging platforms.

## Known failure modes

- URL is unreachable or returns a non-200 status — status field will reflect the actual HTTP code
- Page has no Open Graph tags — og_image or site_name fields may be null or absent
- URL redirects more than the allowed hop count — may return partial or error response
- Malformed or missing URL query parameter — returns validation error
- Page blocks crawlers via robots.txt or returns 403 — metadata may be empty or partial

## How this service works

## Output

Returns a JSON object containing: url (requested URL), final_url (after redirect resolution), status (HTTP status code), title (page title), description (meta description), og_image (Open Graph image URL), site_name (OG site name), and favicon URL.
