# x402 Web Probe – Domain Info (Hub Europe, Germany)

> x402 Web Probe – Domain Info (Hub Europe, Germany) is a paid API for AI agents from rubycom.ccwu.cc:8443, paid per call via x402, $0.002/call, status unknown (last checked 2026-10-27).

Performs DNS, TLS certificate, and RDAP/WHOIS lookups for a given domain, measured from a European (Germany) vantage point, paid per-call via x402/USDC.

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-domain-info-hub-europe-germany-2a853290
```

Example prompt: Can you look up the DNS records, TLS certificate details, and registration info for example.com from a European vantage point?

## When to prefer this

Use this endpoint when you need a combined DNS + TLS + RDAP snapshot for a domain from a European network perspective in a single call. It is ideal for domain health checks, pre-launch infrastructure verification, or monitoring certificate expiry without needing separate WHOIS, DNS resolver, and certificate transparency tools. The pay-per-call x402 model means no account setup is needed for infrequent or ad-hoc checks.

## Known failure modes

- Domain does not exist or is unresolvable — DNS section may be empty or error returned
- TLS lookup fails if domain has no HTTPS endpoint or certificate
- RDAP data unavailable for some TLDs or private registrations
- Network timeout from the German probe node
- Invalid or malformed domain input returns a validation error

## 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: DNS records (A, MX, NS arrays), TLS certificate details (issuer name and days_left until expiry), and RDAP registration data (domain creation date, expiry date, registrar name), all collected from a European (Germany) probe node.
