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

> x402 Web Probe – Domain Info (Hub Europe, Germany) is a paid API for AI agents from webthree.ccwu.cc:8443, paid per call via x402, $0.002/call, status unknown (last checked 2026-10-22).

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

## Facts

- Endpoint: GET https://webthree.ccwu.cc:8443/v1/domain?utm_source=zero.xyz
- Price: $0.002/call

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-7ae70bc5
```

Example prompt: Can you look up the DNS records, TLS certificate status, and registration details for example.com from the European probe?

## When to prefer this

Choose this endpoint when you need a combined DNS + TLS + RDAP snapshot for a domain in a single call, without needing an account or API key, and when European vantage-point measurement matters. Prefer it over separate DNS/WHOIS tools when you want a unified pay-per-call response with no subscription overhead.

## Known failure modes

- Domain does not exist or is unresolvable — DNS fields may be empty or null
- TLS lookup fails if the domain has no HTTPS endpoint or certificate
- RDAP data unavailable for some TLDs or private registrations
- Invalid or malformed domain input returns an error
- Network timeout from the European probe location

## 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 DNS records (A, MX, NS), TLS certificate details (issuer and days until expiry), and RDAP registration data (creation date, expiry date, registrar) for the queried domain.
