# x402 Web Probe — Hub Europe (Germany)

> x402 Web Probe — Hub Europe (Germany) is a paid API for AI agents from arandar.ccwu.cc:8443, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-27).

Checks website uptime, HTTP status, TLS certificate validity, and DNS/TTFB/total latency from a German vantage point, returning structured JSON results.

## Facts

- Endpoint: GET https://arandar.ccwu.cc:8443/v1/check?utm_source=zero.xyz
- Price: $0.001/call
- Payment: x402

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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-9030cc60
```

Example prompt: Can you check if https://example.com is up and responding quickly from Germany — I want to see the HTTP status, TLS certificate details, and how long DNS and the full request take?

## When to prefer this

Choose this endpoint when you need a lightweight, no-account-required uptime or latency probe specifically measured from a European (German) vantage point, and you want structured data including TLS cert health, DNS timing, TTFB, and redirect chain in a single call for $0.001 USDC. Prefer it over generic ping tools when TLS validation or European geographic perspective matters.

## Known failure modes

- URL not publicly accessible or behind firewall — returns ok: false with connection error
- Non-standard ports (not 80/443) are not supported — request will be rejected
- Invalid or malformed URL — schema validation error before request is made
- TLS handshake failure on target — tls.authorized: false with error details
- Payment not processed via x402 — HTTP 402 returned before probe executes
- Target site extremely slow — timeout may cause ok: false with timing data

## 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: whether the site is up (ok boolean), HTTP status code, resolved IP, final URL after redirects, redirect chain array, TLS details (issuer, days remaining, authorization status), timing breakdown (dns_ms, ttfb_ms, total_ms), and the measurement node region (Hub Europe, Germany).
