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/dns-recon)
Output
Returns live DNS resolution data (IPv4 A records and IPv6 AAAA records), TLS certificate metadata (issuer CA, subject, validity/expiry dates), and an HTTP security headers assessment including a security grade — all gathered in real time from the target domain.
Example use cases
Competitor domain security audit
“Run a security recon on openai.com — I want to know its DNS resolution, TLS certificate issuer and expiry date, and what grade its HTTP security headers get.”
Pre-launch SSL certificate check
“Before we go live, can you check that our domain acme-startup.com has a valid TLS certificate, who issued it, and when it expires?”
Third-party vendor due diligence
“I need to vet a vendor — can you pull the DNS records, TLS cert details, and HTTP security header grade for payments.vendor-corp.com so I can assess their security posture?”
Technical details
Endpoint
GEThttps://shopify-spy.agentdiet.dev/v1/dns-recon?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a combined, single-call OSINT snapshot of a domain's DNS resolution, TLS/SSL certificate state, and HTTP security posture — especially for competitive intelligence, third-party vendor due diligence, pre-launch verification, or automated security monitoring pipelines. It is preferable over generic WHOIS tools when you specifically need live certificate and security header data in one response.
Side effects
- Domain does not exist or cannot be resolved — returns DNS lookup failure
- Domain has no TLS certificate (HTTP-only) — TLS fields may be absent or null
- Connection timeout if the target domain is unreachable or rate-limiting
- Invalid domain string format — validation error returned
- Domain resolves but HTTP server does not respond — security headers section may be incomplete
