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/cert-transparency)
Output
Returns live DNS resolution results (IPv4/IPv6 addresses), TLS certificate details (issuer, expiry date), and an HTTP security headers assessment including a security grade for the queried domain.
Example use cases
Pre-acquisition domain security audit
“We're about to acquire a company and I want to check the TLS certificate details, DNS setup, and HTTP security grade for their main domain acmecorp.com — can you pull that OSINT for me?”
SSL certificate expiry monitoring
“Can you check when the TLS certificate for stripe.com expires and who issued it? I want to make sure it's not about to lapse.”
Competitor infrastructure reconnaissance
“Do an OSINT check on openai.com — I want to see their IPv4 and IPv6 DNS records, TLS certificate issuer, and whether their HTTP security headers are properly configured.”
Technical details
Endpoint
GEThttps://company-enrich.agentdiet.dev/v1/cert-transparency?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a quick, all-in-one OSINT snapshot of a domain's live DNS, TLS certificate health, and HTTP security posture without setting up separate DNS lookup, certificate transparency log, and header inspection tools. Ideal for security audits, pre-deal due diligence, threat intelligence, or compliance checks where domain infrastructure transparency is required.
Side effects
- Domain does not exist or has no DNS records — returns empty or error response
- Domain is unreachable or times out during live inspection — returns timeout error
- Invalid domain format provided — returns validation error
- TLS certificate is missing or self-signed — partial data returned
- HTTP security headers not present — grade may be low or absent
