## 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-page-metadata-extractor-f9bb0fb0 -d '<json body>'
```

Example prompt: Can you pull the page metadata — title, description, and Open Graph tags — from this URL: https://example.com/article/best-practices?

## When to prefer this

Choose this endpoint when you need lightweight, structured metadata extraction from a public web page URL — particularly for building link previews, enriching content feeds, or auditing SEO tags — and you want a pay-per-call model via x402 rather than managing a scraping infrastructure subscription. It is best suited for static or server-rendered pages where head metadata is present in the HTML.

## Known failure modes

- Target URL is unreachable or returns a non-200 status — empty or error response returned
- Page has no meta tags — result object may be sparse or empty
- JavaScript-rendered pages may not have metadata extracted correctly if SSR is not available
- Payment not processed (x402 protocol failure) — request rejected before execution
- Malformed or missing input URL — validation error returned
