How this service works
Inspects live IPv4/IPv6 DNS resolution, TLS certificate issuer/expiry, and HTTP security grade. (Live x402 v2, IETF MPP & MCP endpoint at https://shopify-spy.agentdiet.dev/v1/whois-lookup)
Output
Returns live DNS resolution results (IPv4 and IPv6 addresses), TLS certificate metadata (issuer, expiry date, validity), and an HTTP security headers grade assessing the presence and configuration of headers like HSTS, CSP, X-Frame-Options, and others.
Example use cases
Pre-launch security audit for new site
“Before we go live with our new product site at launchpad-example.com, can you pull the TLS certificate info, check what IPs it resolves to, and tell me how our HTTP security headers score?”
Investigating a suspicious vendor domain
“I got an email from invoices.acme-partner.io — can you check the DNS records, TLS certificate issuer, and security header grade for that domain so I can assess whether it's legit?”
Monitoring competitor infrastructure
“Can you run a full domain OSINT check on shopify.com — I want to see their IPv4/IPv6 DNS resolution, TLS certificate details including expiry date, and their HTTP security header grade?”
Technical details
Endpoint
GEThttps://shopify-spy.agentdiet.dev/v1/whois-lookup?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a quick, combined OSINT snapshot of a domain's DNS infrastructure, TLS certificate health, and HTTP security posture in a single call. It is especially useful for security reconnaissance, vendor due diligence, pre-deployment audits, or investigating suspicious domains — without needing separate DNS lookup, certificate transparency, and header-analysis tools.
Side effects
- Domain does not exist or fails DNS resolution — returns error or empty DNS records
- Domain has no TLS certificate (HTTP-only) — certificate fields may be null or absent
- Domain is unreachable or times out — returns a timeout or connection error
- Invalid domain format provided — returns validation error
- Security headers not present on the domain — headers section may return empty or low grade
