## 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 geekvault-web-metadata-extractor-1355b368
```

Example prompt: Can you pull the title, description, and Open Graph image for https://stripe.com so I can use them in a link preview card?

## When to prefer this

Use this endpoint when you need lightweight, structured metadata extraction from a URL without running a full browser or scraping the entire page body. Ideal for generating link previews, enriching bookmark/content databases, auditing SEO tags, or checking Open Graph data before publishing. Requires no API key or signup — pay $0.003 USDC per call via x402 on Base.

## Known failure modes

- URL is unreachable or returns non-2xx status — fields may be null or call may error
- Page blocks crawlers (e.g. 401/403) — metadata may be unavailable
- Page has no Open Graph tags — og_* fields return null
- Malformed or missing URL input — request rejected
- Dynamic/JS-rendered pages where meta tags are injected client-side may not be captured

## How this service works
