## 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 shelf-thirdmade-net-page-meta-extractor-6d01d22b
```

Example prompt: Can you pull the OG tags, page title, canonical URL, and meta description from https://www.example.com/blog/my-article so I can build a link preview for it?

## When to prefer this

Choose this endpoint when you need lightweight, fast extraction of only the metadata layer of a page (OG tags, title, canonical, meta description) without the full page body text. It is ideal for link preview generation, SEO auditing, and content enrichment workflows where you do not need the full page content. For full page text and body content, prefer the sibling scrape endpoint on shelf.thirdmade.net.

## Known failure modes

- Target URL is unreachable or returns a non-200 status — extraction fails with an error
- Page blocks crawlers via robots.txt or firewall — may return empty or partial metadata
- Page uses JavaScript-rendered content only — static meta tags may be missing
- Malformed or missing meta tags on the page — fields return null or empty strings
- Invalid URL format in query parameter — returns validation error

## How this service works

Extracts OG tags, canonical URL, title, and meta description from any web page. Useful for link previews, SEO audits, and content enrichment.

## Output

Returns structured metadata extracted from the target webpage, including Open Graph tags (og:title, og:description, og:image, og:url), the canonical URL, the HTML page title, and the meta description tag.
