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://mcp-compiler.agentdiet.dev/v1/osint)
Output
Returns live DNS resolution results (IPv4 and IPv6 addresses), TLS certificate details including issuer and expiry date, and an HTTP security header grade assessing the domain's security posture.
Example use cases
SSL certificate expiry check for vendor
“Check the TLS certificate for stripe.com — I need to know who issued it and when it expires so I can flag it in our vendor security review.”
Security header audit before launch
“Before we go live, can you audit the HTTP security headers on staging.myapp.com and tell me what grade it gets?”
IPv6 readiness verification
“Does cloudflare.com resolve over IPv6? Can you do a live DNS lookup and show me both the IPv4 and IPv6 addresses?”
Technical details
Endpoint
GEThttps://mcp-compiler.agentdiet.dev/v1/osint?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a fast, single-call OSINT snapshot of a domain's network security posture, combining DNS, TLS, and HTTP security headers in one response. Prefer it over manual nslookup or curl when you need structured, machine-readable output suitable for automated security audits, vendor assessments, or pre-launch checks.
Side effects
- Domain does not exist or fails DNS resolution — returns error or empty DNS results
- Domain has no TLS certificate (plain HTTP only) — TLS fields may be null or absent
- Domain blocks the probe IP — may return timeout or incomplete data
- Malformed domain input — returns validation error
- Temporary network issues causing incomplete recon results
