Domain OSINT, TLS Certificate & Security Headers Recon
Domain OSINT, TLS Certificate & Security Headers Recon is a paid API for AI agents from email-verify.agentdiet.dev, paid per call via MPP, $0.01/call, status unknown (last checked 2026-10-21).
Performs live reconnaissance on a domain's DNS resolution (IPv4/IPv6), TLS certificate details (issuer, expiry), and HTTP security headers grade.

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://email-verify.agentdiet.dev/v1/dns-whois-tls-recon)
Output
Returns live DNS resolution results (IPv4/IPv6 addresses), TLS certificate metadata (issuer, expiry date), and an HTTP security headers grade/score for the target domain.
Example use cases
Pre-launch security audit of own domain
“Before we go live, can you check openai.com's TLS certificate — who issued it, when it expires — and give me a grade on the HTTP security headers?”
Competitive domain infrastructure intel
“I want to do some recon on stripe.com — pull its DNS records including IPv4 and IPv6 addresses, TLS cert details, and security header grade so I can benchmark against our own setup.”
Suspicious domain investigation
“There's a sketchy domain phishing-attempt-example.net that showed up in our logs — can you inspect its DNS resolution, TLS certificate issuer, and security headers to help me assess if it's legitimate?”
Technical details
Endpoint
GEThttps://email-verify.agentdiet.dev/v1/dns-whois-tls-recon?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need live, real-time domain security intelligence combining DNS resolution, TLS certificate details, and HTTP security header grades in a single call — particularly for OSINT workflows, security audits, phishing investigations, or competitive infrastructure analysis where freshness matters.
Side effects
- Domain does not exist or has no DNS records — returns empty or error response
- Domain is unreachable or times out during live probe
- Invalid domain input (malformed string) — returns validation error
- Domain has no HTTPS/TLS — TLS fields may be null or absent
- HTTP security headers unavailable if domain blocks probes or returns non-2xx
