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

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://mesh.agentdiet.dev/v1/ssl-audit)
Output
Returns live DNS resolution results (IPv4/IPv6 addresses), TLS certificate details (issuer, expiry date, validity status), and an HTTP security header audit including presence and grade of headers such as HSTS, CSP, X-Frame-Options, and related security signals.
Example use cases
Pre-launch security check on new domain
“Before we go live, can you audit our domain startupapp.io — I want to see the DNS resolution, who issued our TLS cert and when it expires, and whether our security headers are properly configured?”
Competitor domain OSINT research
“Do a quick security and DNS recon on openai.com — I want to know their IPv4 and IPv6 addresses, who issued their SSL certificate and when it expires, and how their HTTP security headers score.”
Alert on expiring SSL certificate
“Check stripe.com's TLS certificate — I'm worried it might be close to expiring. Tell me the issuer, expiry date, and pull the DNS records while you're at it.”
Technical details
Endpoint
GEThttps://mesh.agentdiet.dev/v1/ssl-audit?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a combined DNS + TLS + HTTP security header snapshot for a domain in a single low-latency call. Prefer it over separate DNS lookup tools, SSL checkers, or security header scanners when you want consolidated OSINT without chaining multiple APIs. Particularly useful for security audits, pre-launch checks, competitive reconnaissance, or monitoring certificate expiry across a set of domains.
Side effects
- Domain does not exist or fails DNS resolution — returns error or empty DNS results
- Domain has no HTTPS endpoint — TLS certificate fields unavailable
- Rate limiting or network timeout reaching the target domain — partial or failed response
- Invalid domain format in input — validation error returned
- Domain exists but HTTP server is unreachable — security headers cannot be retrieved
