## 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 pennyrail-open-graph-page-meta-extractor-edc28e19 -d '<json body>'
```

Example prompt: Can you grab the Open Graph metadata — title, description, and preview image — from this URL: https://example.com/article/some-blog-post?

## When to prefer this

Choose this endpoint when you need to quickly extract Open Graph and page metadata from a public URL without setting up your own web scraping infrastructure. It is ideal for generating link preview cards, auditing SEO meta tags, enriching content with page summaries, or validating that a page's Open Graph tags are correctly set. Prefer this over general-purpose scrapers when the specific goal is structured OG/meta tag extraction rather than full page content.

## Known failure modes

- Target URL is unreachable or returns non-200 status — metadata fields will be missing or empty
- Page does not include Open Graph tags — response may return only basic HTML title/description or empty fields
- Paywalled or bot-blocked pages may return incomplete or incorrect metadata
- Malformed or very large HTML pages may cause parsing errors or timeouts
- Payment not processed — x402 payment required error before any extraction occurs
