## 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-web-page-metadata-extractor-5735b94d -d '<json body>'
```

Example prompt: Can you grab the page metadata — title, description, and any Open Graph tags — for https://example.com/some-article so I can use it in a link preview?

## When to prefer this

Choose this endpoint when you need a lightweight, paid-per-call web page metadata extraction without setting up your own scraper infrastructure. It is well-suited for link preview generation, SEO auditing, or content enrichment pipelines where you need title/description/OG tags from arbitrary URLs. Prefer it over general-purpose scraping endpoints when you specifically need structured head metadata rather than full page content.

## Known failure modes

- Target URL is unreachable or returns a non-200 status — empty or error response returned
- Target page has no meta tags — response object may be sparse or empty
- Invalid or malformed URL input — request fails with validation error
- Page blocks server-side crawlers — metadata extraction returns partial or no results
- Payment not processed — 402 response returned before data is delivered
