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://company-enrich.agentdiet.dev/v1/osint)
Output
Returns live DNS resolution data (IPv4/IPv6 addresses), TLS certificate metadata (issuer, expiry date), and an HTTP security headers analysis with a security grade for the target domain.
Example use cases
Pre-vendor security due diligence
“Before we sign a contract with this SaaS vendor, can you check their domain openai.com for DNS resolution, TLS certificate validity, and how their HTTP security headers score?”
Monitor competitor TLS expiry
“Can you pull the TLS certificate expiry and issuer info for stripe.com so I can track when their cert is due for renewal?”
Audit own domain security posture
“Run a full OSINT check on mycompany.com — I want to see our IPv4 and IPv6 DNS records, our SSL cert details, and our HTTP security header grade.”
Technical details
Endpoint
GEThttps://company-enrich.agentdiet.dev/v1/osint?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a quick, live, all-in-one domain security snapshot covering DNS, TLS, and HTTP security headers in a single call. Prefer it over general WHOIS tools when you specifically need certificate expiry/issuer and security header grading, or over manual nmap/curl workflows when you want structured, agent-consumable output at low cost ($0.01/call).
Side effects
- Domain does not exist or fails to resolve — returns DNS lookup error
- Domain is unreachable over HTTPS — TLS certificate data unavailable
- HTTP connection refused — security headers cannot be evaluated
- Invalid or empty domain parameter — returns validation error
- Domain resolves but has no TLS (HTTP only) — certificate fields empty
