## 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-fetch-to-markdown-hub-europe-germany-10745717
```

Example prompt: Fetch the page at https://example.com and give me its content as Markdown — I want to see the title and whether it returned a 200 status, measured from the European hub.

## When to prefer this

Choose this endpoint when you need to fetch and read the content of a public webpage as Markdown from a European network location, especially for monitoring EU-region uptime, extracting readable content without an API key, or verifying geo-specific responses from Germany. Prefer it over generic scrapers when you want pay-per-call pricing with no account setup and a known European probe origin.

## Known failure modes

- Non-200 HTTP status returned if target site is down or returns an error
- Timeout or connection failure if target site is unreachable from Germany
- Truncated Markdown if the page content exceeds the service size limit (truncated: true)
- Invalid or non-public URLs will result in an error response
- TLS errors if the target site has an invalid certificate

## How this service works

Pay-per-call website uptime/latency/TLS checks and fetch-to-Markdown, measured from Hub Europe (Germany). USDC on Base via x402. No account or API key.

## Output

Returns a JSON object containing the page URL, the extracted page title, the HTTP status code (e.g. 200), the full page body converted to Markdown text, and a boolean indicating whether the content was truncated. Measured from a European (Germany) network vantage point.
