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-intel.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 header grade reflecting the presence or absence of headers like HSTS, CSP, X-Frame-Options, and similar security controls.
Example use cases
Vendor security due diligence check
“Before we onboard this new SaaS vendor, can you check openai.com's TLS certificate details, DNS setup, and HTTP security headers so I know if their web security posture looks solid?”
SSL certificate expiry monitoring
“Can you check when the TLS certificate for stripe.com expires and who issued it? I want to make sure it's not about to lapse.”
Competitor web security audit
“I'm doing a competitive analysis — can you pull the DNS records, TLS certificate info, and security header grade for shopify.com so I can compare their web security setup to ours?”
Technical details
Endpoint
GEThttps://shopify-intel.agentdiet.dev/v1/whois-lookup?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a combined, real-time OSINT snapshot covering DNS, TLS, and HTTP security headers in a single call — ideal for security due diligence, vendor assessments, certificate expiry monitoring, and competitive web security analysis. Prefer this over standalone WHOIS or certificate transparency tools when you need live, multi-signal domain intelligence in one request at low cost.
Side effects
- Domain does not exist or fails to resolve — returns DNS lookup failure
- Domain has no TLS certificate or HTTPS endpoint — TLS fields may be null or absent
- Invalid domain input (empty string, malformed) — validation error returned
- Domain is unreachable or times out — connection timeout error
- Payment not completed (HTTP 402) — request blocked until x402 payment is fulfilled
