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 the resolved IP, final URL, HTTP status code, boolean ok flag, TLS certificate details (issuer, days_left, authorized), DNS/TTFB/total timing in milliseconds, redirect chain, and the probe region/node identifier — all measured from the Germany vantage point.
Example use cases
European uptime check for SaaS app
“Is https://myapp.io currently reachable from Germany? I need the HTTP status code, whether the TLS cert is valid, and the total response time.”
SSL certificate expiry monitoring
“Check https://shop.mybrand.com from the European probe and tell me how many days are left on the TLS certificate and who issued it.”
Redirect chain inspection from Europe
“Can you probe https://bit.ly/my-short-link from Germany and show me all the redirects it follows plus the final destination URL and its HTTP status?”
Technical details
Endpoint
GEThttps://crystalbell.ccwu.cc:8443/v1/check?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a lightweight, no-account, pay-per-call uptime or TLS check specifically from a European (Germany) geographic vantage point, with structured JSON output including timing, certificate info, and redirect chains. Prefer it over traditional monitoring services when you want microtransaction pricing with no subscription, or when verifying European accessibility of a site specifically. Not suited for fetching full page content for parsing or for non-HTTP protocols.
Side effects
- URL is not publicly reachable on port 80 or 443 — endpoint rejects non-standard ports
- Target host DNS resolution fails — returns error with no timing data
- TLS certificate is invalid or expired — ok=false, authorized=false in tls object
- Payment via x402/USDC on Base fails — request is rejected before probe runs
- Non-GET method requested — schema validation error since only GET is supported
- Target URL times out — partial timing data returned with ok=false
