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 left until expiry), and RDAP registration data (creation date, expiry date, registrar name), all probed from a European vantage point.
Example use cases
SSL certificate expiry monitoring
“Check the TLS certificate for mybusiness.com from Europe — I want to know who issued it and how many days are left before it expires.”
Domain registration due-diligence
“Look up the RDAP registration info for competitor-site.com — I need the registrar name, creation date, and expiry date.”
DNS record audit for a new domain
“Pull the DNS records for startup.io — show me the A records, MX records, and nameservers as seen from Germany.”
Technical details
Endpoint
GEThttps://kollmz.site:8443/v1/domain?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a fast, one-call lookup of a domain's DNS, TLS, and RDAP data from a European network vantage point with no API key or account required — ideal for agents that need pay-per-use infrastructure checks without onboarding. Prefer it over general web scrapers when the target data is specifically DNS/TLS/RDAP metadata rather than page content.
Side effects
- Domain does not exist or is unresolvable — DNS fields may be empty or absent
- TLS lookup fails if domain has no HTTPS endpoint — tls field may be null or missing
- RDAP data unavailable for some TLDs — rdap field may be empty
- Invalid or malformed domain input returns a validation error
- Network timeout from the European probe node — transient failure, retry recommended
- Payment not completed via x402 — request rejected with HTTP 402
