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

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

Looks up DNS records, TLS certificate details, and RDAP registration data for a given domain, measured from a European vantage point, billed 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-lookup-hub-europe-germany-dbde8a85
```

Example prompt: Can you check the DNS records, TLS certificate status, and registration info for stripe.com from the European probe — I want to see the A records, who issued the cert and how many days it has left, and when the domain expires?

## When to prefer this

Choose this endpoint when you need a combined DNS + TLS + RDAP snapshot of a domain from a European network vantage point, without setting up an account or API key. It is ideal for one-off domain health checks, pre-launch verifications, or monitoring tasks where European geographic perspective matters. It is not suited for continuous high-frequency monitoring (cost per call) or for fetching page content (use the fetch/markdown sibling endpoint for that).

## Known failure modes

- Domain not found or does not exist — empty or null DNS/RDAP fields
- TLS lookup fails for non-HTTPS domains — tls object may be empty
- RDAP data unavailable for certain TLDs — rdap fields may be null
- Invalid domain format in query parameter — request rejected
- Payment not completed via x402 — HTTP 402 returned, no data provided
- Network timeout from European probe — intermittent errors for slow-responding domains

## 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: DNS records (A, MX, NS arrays), TLS certificate info (issuer name and days remaining), RDAP registration data (creation date, expiry date, registrar name), and the queried domain string. All data is collected from a European (Germany) vantage point.
