## 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-04294fc6
```

Example prompt: Can you fetch the content of https://news.ycombinator.com and give it to me as Markdown — using the European probe so I get the European version of the page?

## When to prefer this

Choose this endpoint when you need to fetch and read web page content as clean Markdown from a European (German) network vantage point — useful for geo-sensitive content, European compliance checks, or when you want a no-account micropayment model (USDC on Base via x402) instead of a subscription scraping API. It is especially suited for single-URL ad-hoc fetches rather than bulk crawling.

## Known failure modes

- Non-200 HTTP status if the target URL is down or returns an error
- Timeout if the remote server is slow to respond from Germany
- Empty or garbled Markdown if the page is JavaScript-heavy (SPA) and content is dynamically rendered
- Payment failure if USDC balance on Base is insufficient
- Invalid input if the 'url' query parameter is missing or malformed
- TLS errors if the target site has certificate issues

## 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

A JSON object containing the fetched page's URL, title, HTTP status code (e.g. 200), the full page content rendered as Markdown text, and a boolean 'truncated' flag indicating whether the content was cut off due to length limits.
