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/osint)
Output
Returns a structured object containing live IPv4 and IPv6 DNS resolution results, TLS certificate metadata (issuer, expiry date, validity status), and an HTTP security header audit grade for the target domain.
Example use cases
Pre-launch security check for new domain
“Before we go live with our new product site at launchpad-startup.io, can you check its DNS resolution, TLS certificate issuer and expiry date, and HTTP security header grade so we know if anything needs fixing?”
Vendor due diligence domain audit
“We're onboarding a new vendor and I want to verify their domain security — can you pull the DNS records, TLS certificate details, and security header grade for vendorsupplier.com?”
Competitor infrastructure reconnaissance
“I'm doing competitive research — can you check the DNS resolution, SSL certificate issuer and expiry, and HTTP security headers for stripe.com and tell me how their security posture looks?”
Technical details
Endpoint
GEThttps://sec-intel.agentdiet.dev/v1/osint?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a quick, all-in-one domain reconnaissance snapshot covering DNS resolution, TLS certificate health, and HTTP security posture in a single call. It is ideal for pre-deployment security checks, vendor due diligence, threat intelligence workflows, or competitive infrastructure analysis — especially when you need live data rather than cached records.
Side effects
- Domain does not resolve — returns empty or null DNS records
- Domain has no HTTPS/TLS — certificate fields may be absent or error
- Invalid or malformed domain string — API may return validation error
- Unreachable domain (firewall, blackhole) — timeout or connection error
- HTTP security headers unavailable if domain returns non-200 or blocks scanners
