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://sec-intel.agentdiet.dev/v1/ssl-audit)
Output
Returns live IPv4/IPv6 DNS resolution results, TLS certificate metadata (issuer, expiry date, validity status), and an HTTP security headers grade/breakdown for the queried domain.
Example use cases
Pre-launch SSL expiry check
“Can you check when the TLS certificate for my-startup.com expires and who issued it? I want to make sure we're not about to have an outage.”
Competitor security posture OSINT
“Run a security recon on openai.com — I want to see its IPv4 and IPv6 DNS records, TLS certificate details, and how it scores on HTTP security headers.”
Vendor due diligence domain audit
“We're onboarding a new vendor at vendor-portal.example.com. Can you check their DNS resolution, TLS certificate issuer and expiry, and whether they have proper security headers in place?”
Technical details
Endpoint
GEThttps://sec-intel.agentdiet.dev/v1/ssl-audit?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a quick, combined OSINT snapshot of a domain's DNS resolution, TLS certificate health, and HTTP security posture in a single call, rather than orchestrating separate DNS, SSL, and security-header tools. It's especially useful for security audits, vendor due diligence, competitor reconnaissance, or monitoring certificate expiry.
Side effects
- Domain does not exist or cannot be resolved — DNS lookup failure returned
- Domain is unreachable or times out during TLS handshake — connection error
- Domain has no HTTPS endpoint — TLS inspection unavailable
- Invalid or malformed domain string in query parameter — validation error
- Rate limiting or payment failure via x402 — 402 response
