## 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 x402-web-probe-hub-europe-germany-meta-b64f98f5
```

Example prompt: Can you fetch the title, description, OpenGraph tags, and all links from https://example.com — probing it from Europe so I get the European-facing metadata?

## When to prefer this

Choose this endpoint when you need structured page metadata (title, description, OG tags, links, headings) fetched from a European/German vantage point, without needing an API key or account. Ideal for SEO checks, content audits, link extraction, or verifying how a page appears to European crawlers. Prefer it over general scraping services when geographic probing from Germany matters or when a pay-per-call model without subscriptions is preferred.

## Known failure modes

- URL is not publicly accessible or returns a non-200 status — probe reports the error or returns empty fields
- Target site blocks bots or returns a CAPTCHA — metadata may be incomplete or missing
- Invalid or malformed URL input — request fails with a validation error
- Target site is extremely slow — probe may time out
- Private/intranet URLs that are unreachable from the German probe node — no data returned

## How this service works
