How this service works
Pay-per-call website uptime/latency/TLS checks and fetch-to-Markdown, measured from US Central (St. Louis). 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 remaining), RDAP registration data (creation date, expiry date, registrar name), and the queried domain name. All data is measured/resolved from US Central (St. Louis).
Example use cases
Certificate expiry monitoring for a site
“Check the TLS certificate for mybusiness.com and tell me how many days are left before it expires — I want to know if we need to renew soon.”
Domain ownership and registration audit
“Look up the RDAP registration info for acmecorp.io — I need to know when it was created, when it expires, and who the registrar is.”
DNS troubleshooting for email delivery
“Can you pull the DNS records for newsletter-sender.com? I specifically need to see the MX and NS records to debug a mail delivery issue.”
Technical details
Endpoint
GEThttps://rockndefi.xyz:8443/v1/domain?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a quick, structured snapshot of a domain's DNS records, TLS certificate health, and registration details in a single call without requiring an account or API key. It is ideal for lightweight, pay-per-use domain intelligence checks from a US Central vantage point, particularly when integrating with x402 micropayment workflows on Base.
Side effects
- Domain does not exist — DNS lookup returns empty or NXDOMAIN
- TLS check fails if the domain has no HTTPS/SSL endpoint
- RDAP data unavailable for some TLDs or private registrations
- Payment failure via x402/USDC prevents the call from completing
- Timeout if DNS or RDAP servers are slow to respond
- Invalid domain format in query parameter returns an error
