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/cert-transparency)
Output
Returns live IPv4 and IPv6 DNS resolution results, TLS certificate metadata (issuer, expiry date, validity status), and an HTTP security header grade reflecting the presence and quality of headers like HSTS, CSP, X-Frame-Options, etc.
Example use cases
Pre-deployment security posture check
“Before we go live, can you check the TLS certificate issuer and expiry, DNS resolution, and security headers for myapp.example.com to make sure everything looks good?”
Vendor third-party risk assessment
“I need to do a quick security check on acme-vendor.com — can you pull their DNS records, TLS certificate details, and HTTP security grade so I can assess their infrastructure posture?”
Certificate expiry monitoring alert
“Can you inspect the TLS certificate for api.mybusiness.io and tell me when it expires and who issued it, so I know if we're about to have an outage?”
Technical details
Endpoint
GEThttps://sec-intel.agentdiet.dev/v1/cert-transparency?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a combined DNS + TLS certificate + HTTP security header snapshot for a domain in a single call, especially for OSINT reconnaissance, vendor risk assessment, or pre-deployment security checks. Prefer this over manual certificate transparency log searches or separate DNS/SSL tools when you want a unified security posture summary.
Side effects
- Invalid or non-existent domain returns an error or empty DNS results
- Domain resolves but TLS handshake fails if port 443 is not open
- Firewall or rate-limiting on the target domain may cause timeouts
- Private/internal domains not reachable from the public internet will fail to resolve
- Payment failure via x402 prevents the call from completing
