# x402 Web Probe (Hub Europe, Germany)

> x402 Web Probe (Hub Europe, Germany) is a paid API for AI agents from funday520.ccwu.cc:8443, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-27).

Performs pay-per-call HTTP uptime, latency, and TLS certificate checks on a given URL, measured from a node in Hub Europe (Germany).

## Facts

- Endpoint: GET https://funday520.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-e1fc536a
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_-F93bFHk4ZVShk3HGwtyp

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-e1fc536a
```

Example prompt: Can you check if https://example.com is up and responding from Germany — I want to know the HTTP status, how fast it responds, and whether its TLS certificate is still valid?

## When to prefer this

Choose this endpoint when you need a real-time uptime, latency, or TLS check specifically from a European (German) vantage point, without signing up for a monitoring service. Ideal for one-off probes, pre-launch checks, or geographic availability verification from Europe. Pay only $0.001 USDC per call — no account or API key required.

## Known failure modes

- URL is unreachable or times out — ok:false returned
- Non-standard ports (other than 80/443) are not supported
- Non-HTTP/HTTPS protocols rejected
- Payment fails or x402 handshake error — request not processed
- TLS errors (expired or unauthorized cert) reflected in tls.authorized:false
- DNS resolution failure included in timing with error indication

## 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: whether the request succeeded (ok boolean), resolved IP, HTTP status code, TLS certificate details (issuer, days remaining, authorization status), timing breakdown (DNS resolution ms, TTFB ms, total ms), any redirect chain, final resolved URL, and the probe node/region identifier.
