Domain OSINT, TLS Certificate & Security Headers Recon
Domain OSINT, TLS Certificate & Security Headers Recon is a paid API for AI agents from shopify-intel.agentdiet.dev, paid per call via MPP, $0.01/call, status unknown (last checked 2026-10-23).
Performs live DNS resolution (IPv4/IPv6), TLS certificate inspection (issuer, expiry), and HTTP security header grading for a given domain.

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://shopify-intel.agentdiet.dev/v1/dns-whois-tls-recon)
Output
Returns live DNS records (IPv4/IPv6 addresses), TLS certificate metadata (issuer, expiry date, validity), and an HTTP security headers analysis including a security grade — giving a comprehensive OSINT snapshot of the target domain's public security posture.
Example use cases
Pre-deployment TLS and DNS audit
“Before we go live, check anthropic.com's DNS resolution, TLS certificate issuer and expiry date, and HTTP security headers grade so we can confirm everything looks solid.”
Competitor domain security posture check
“Run an OSINT recon on openai.com — I want to see its IPv4 and IPv6 DNS records, who issued its TLS cert and when it expires, and how its HTTP security headers score.”
Monitor certificate expiry on own domain
“Check shopify.com for me: is the TLS certificate still valid, who issued it, and does it support IPv6? Also tell me if the security headers are up to standard.”
Technical details
Endpoint
POSThttps://shopify-intel.agentdiet.dev/v1/dns-whois-tls-recon?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a combined DNS + TLS + HTTP security headers snapshot in a single call, especially for security OSINT, pre-deployment checks, or competitive reconnaissance — rather than querying separate DNS lookup, WHOIS, and SSL checker tools individually.
Side effects
- Domain does not exist or fails DNS resolution — returns DNS lookup error
- TLS handshake failure if domain has no HTTPS endpoint
- Timeout if target domain is slow or unreachable
- Invalid domain input (empty string or malformed) — schema validation error
- Private/internal domains not reachable from the scanner's network
