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: whether the request succeeded (ok), the resolved IP address, HTTP status code, TLS details (issuer, days remaining, authorization status), timing breakdown (DNS resolution ms, TTFB ms, total ms), redirect chain, and final URL — all measured from the Hub Europe (Germany) node.
Example use cases
E-commerce uptime check from Europe
“Is https://shop.mystore.com responding correctly from Germany right now? I need to know the HTTP status, whether the SSL cert is valid, and how long it's taking to respond.”
SSL certificate expiry monitoring
“Check https://api.mybusiness.com from Europe and tell me how many days are left on the TLS certificate and who issued it — I want to make sure we don't let it expire.”
Redirect chain verification
“Can you probe https://old.mysite.com from your European node and tell me if it's redirecting properly to the new domain, and what the final URL ends up being?”
Technical details
Endpoint
GEThttps://kollmz.site:8443/v1/check?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a European (Germany) vantage point for HTTP uptime, latency, or TLS checks without requiring an account or API key, paying only $0.001 USDC per call via x402. Prefer it over self-hosted monitoring when you need an external perspective from Europe, or over account-based services when you want frictionless pay-per-use access.
Side effects
- Target URL is unreachable or returns a non-2xx status — ok=false is returned with available timing data
- TLS certificate is invalid or expired — authorized=false with days_left potentially negative
- URL does not use port 80 or 443 — request may be rejected or fail
- Invalid or malformed URL input — request rejected
- Payment not completed via x402/USDC — endpoint returns 402 before probe executes
