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/dns-whois-tls-recon)
Output
Returns live DNS resolution results (IPv4 and IPv6 addresses), TLS certificate metadata (issuer, expiry date, chain details), and an HTTP security headers inspection with a security grade — giving a comprehensive snapshot of the domain's infrastructure and security posture.
Example use cases
Vendor security due diligence
“I need to vet a new SaaS vendor before we sign a contract — can you check the DNS resolution, TLS certificate issuer and expiry, and HTTP security headers for stripe.com so I can assess their infrastructure posture?”
SSL certificate expiry monitoring
“We're worried about certificate lapses — can you check when the TLS certificate for api.example.com expires and who issued it?”
Competitor domain OSINT
“Do a quick OSINT check on openai.com: what IPv4 and IPv6 addresses does it resolve to, what's the TLS cert issuer and expiry date, and how do their HTTP security headers grade?”
Technical details
Endpoint
GEThttps://mesh.agentdiet.dev/v1/dns-whois-tls-recon?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a combined, single-call recon of DNS records, TLS certificate metadata, and HTTP security headers for any domain — ideal for security audits, vendor due diligence, certificate expiry checks, or OSINT investigations where you want infrastructure intelligence without assembling multiple separate tools.
Side effects
- Domain does not exist or fails DNS resolution — returns error or empty DNS results
- Domain is unreachable over HTTPS — TLS certificate data may be unavailable
- Domain has no IPv6 records — IPv6 field may be empty
- HTTP security headers unavailable if server does not respond to HTTP/HTTPS requests
- Invalid domain format submitted — returns validation error
- Payment not completed via x402 — returns 402 Payment Required
