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/ssl-audit)
Output
Returns live IPv4 and IPv6 addresses resolved for the domain, TLS certificate metadata (issuer, validity dates, expiry), and an HTTP security headers analysis including a security grade, giving a full OSINT snapshot of the domain's network and TLS posture.
Example use cases
Pre-acquisition domain security due diligence
“We're considering acquiring a startup — can you pull the TLS cert issuer and expiry, IPv4/IPv6 DNS records, and HTTP security header grade for theirdomain.com so I can assess their infrastructure hygiene?”
Alert on expiring SSL certificate
“Check acme-corp.com's TLS certificate right now — I need to know the expiry date and who issued it so I can tell if we're at risk of an imminent cert expiry.”
Competitor security posture benchmarking
“Run a DNS and security headers recon on competitor.io — I want to see their IP resolution, TLS cert details, and HTTP security grade to benchmark against our own setup.”
Technical details
Endpoint
GEThttps://shopify-spy.agentdiet.dev/v1/ssl-audit?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need live, real-time DNS, TLS, and HTTP security header data for a single domain in one call — ideal for security reconnaissance, due diligence on vendor or acquisition targets, monitoring certificate expiry, or benchmarking competitor security posture. Prefer this over manual nmap/curl workflows or separate DNS/SSL checker tools when you need a unified OSINT snapshot with a security grade in a single API call.
Side effects
- Domain does not exist or fails DNS resolution — empty or error response
- Domain has no HTTPS endpoint — TLS certificate data absent
- Network timeout reaching the target domain — partial or null results
- Invalid domain format provided — validation error
- Domain is unreachable from probe infrastructure — connectivity error
