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

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

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

## Facts

- Endpoint: GET https://crystalbell.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-da7df10d
```

Example prompt: Can you look up the DNS records, TLS certificate status, and registration info for example.com using 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, especially when a European vantage point is relevant (e.g. for GDPR-region checks or EU-hosted infrastructure). It requires no API key — only a micropayment via x402/USDC on Base. Prefer it over manual whois or separate DNS APIs when you want structured JSON output covering all three data types at once.

## Known failure modes

- Domain not found or invalid hostname returns empty or error response
- TLS lookup fails if the domain has no HTTPS endpoint
- RDAP data unavailable for certain TLDs or reserved domains
- Network timeout if the target domain is unreachable from the European hub
- Payment failure or x402 rejection if USDC balance is insufficient

## 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, days until expiry), and RDAP registration info (creation date, expiry date, registrar name) for the queried domain.
