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: whether the site is reachable (ok: boolean), HTTP status code, resolved IP, final URL after redirects, list of redirects, DNS latency in ms, TTFB in ms, total response time in ms, TLS certificate issuer, days remaining on the certificate, TLS authorization status, and the probe region/node identifier (Hub Europe, Germany).
Example use cases
European uptime check for SaaS product
“Is https://app.mycompany.com currently reachable and returning a 200 from Europe? Also tell me the TLS certificate expiry and DNS timing.”
SSL certificate expiry monitoring
“Check https://store.mybrand.com from your Germany node and tell me how many days are left on the TLS certificate and who issued it — I want to know if it's about to expire.”
Redirect chain and final URL verification
“Can you probe https://short.link/abc from the German vantage point and tell me what the final destination URL is and whether there are any redirects along the way?”
Technical details
Endpoint
GEThttps://rabbitholeshot.ccwu.cc:8443/v1/check?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a quick, pay-as-you-go website uptime or TLS health check from a European (Germany) network vantage point, with no account or API key setup required. Prefer it over subscription-based monitoring tools for one-off or infrequent checks, for validating European reachability specifically, or when you need micropayment-friendly infrastructure checks inside an automated agent workflow.
Side effects
- URL is unreachable or times out — ok: false returned with partial timing data
- Non-80/443 port specified — rejected or unsupported
- Invalid or malformed URL input — schema validation error
- TLS certificate expired or unauthorized — tls.authorized: false, days_left near 0
- Site returns non-200 status — captured in status field, ok may still be false
- DNS resolution failure — dns_ms may be missing or error returned
- Payment not settled via x402 — request blocked with HTTP 402 before probe executes
