Domain OSINT, TLS Certificate & Security Headers Recon
Domain OSINT, TLS Certificate & Security Headers Recon is a paid API for AI agents from serp-extract.agentdiet.dev, paid per call via MPP, $0.01/call, status unknown (last checked 2026-10-23).
Inspects a target domain's live DNS resolution (IPv4/IPv6), TLS certificate details (issuer, expiry), and HTTP security header grade in a single call.

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://serp-extract.agentdiet.dev/v1/domain-osint)
Output
Returns a structured object containing the domain's live IPv4 and IPv6 DNS resolution results, TLS certificate metadata (issuer, validity dates, expiry status), and an HTTP security headers analysis including grade or score — giving a comprehensive snapshot of the domain's network and security configuration.
Example use cases
Pre-launch security audit of own domain
“Before we go live, can you check our domain acmecorp.io for its TLS cert issuer and expiry, IPv4/IPv6 DNS resolution, and give me the HTTP security headers grade?”
Investigating a suspicious phishing domain
“I got a phishing report about the domain secure-login-bankofamerica.net — can you run an OSINT recon on it to see what IPs it resolves to, who issued its TLS cert, and whether it has proper security headers?”
Competitive security benchmarking
“I want to benchmark our security posture against our competitor — can you pull the DNS records, TLS certificate details, and HTTP security grade for shopify.com so I can compare?”
Technical details
Endpoint
POSThttps://serp-extract.agentdiet.dev/v1/domain-osint?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a fast, single-call snapshot combining DNS resolution, TLS certificate inspection, and HTTP security header analysis for any domain — ideal for OSINT workflows, security audits, phishing investigations, or compliance checks where you need all three signals together rather than querying separate tools.
Side effects
- Domain does not resolve — DNS lookup fails, returns error or empty IP fields
- TLS certificate absent or expired — cert details may be null or contain expiry warnings
- Domain unreachable over HTTP/HTTPS — security headers cannot be fetched
- Invalid domain input (e.g. malformed string) — validation error returned
- Target blocks automated probes — incomplete or partial data returned
