# x402 Web Probe – Hub Europe (Germany)

> x402 Web Probe – Hub Europe (Germany) is a paid API for AI agents from rubycom.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 health, and latency from a German node, returning structured diagnostics including DNS, TTFB, and total response time.

## Facts

- Endpoint: GET https://rubycom.ccwu.cc:8443/v1/check?utm_source=zero.xyz
- Price: $0.001/call
- Payment: x402
- Status: unknown
- Last checked: 2026-10-27
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/x402-web-probe-hub-europe-germany-7e1a7926
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_em5RBj2_UU2VwxzvlqRzY

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-7e1a7926
```

Example prompt: Can you check if https://mystore.com is up right now, and tell me the HTTP status, TLS certificate days remaining, and how fast it responds — measured from Germany?

## When to prefer this

Choose this endpoint when you need a European geographic vantage point for uptime or latency checks, or when you want combined HTTP status + TLS certificate + timing data in a single call without setting up an account. It is ideal for one-off or agent-driven probes at $0.001 per call with no API key required, paid via USDC on Base (x402 protocol).

## Known failure modes

- URL is not publicly reachable or uses non-standard port (only 80/443 supported) — ok:false returned
- TLS certificate invalid or expired — tls.authorized:false with days_left near zero
- DNS resolution failure — dns_ms absent or error flag in response
- Timeout if target server is extremely slow or unreachable
- Payment (x402 USDC on Base) fails or is rejected — request not processed
- Non-HTTP/HTTPS schemes or private IPs may be rejected by the probe

## 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 with: ok (boolean), HTTP status code, resolved IP, final URL after redirects, redirect chain, TLS info (issuer, days_left, authorized), timing breakdown (dns_ms, ttfb_ms, total_ms), and the probe node/region identifier (Hub Europe, Germany).
