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/osint)
Output
Returns live IPv4 and IPv6 DNS resolution results, TLS certificate details (issuer, expiry date, validity status), and an HTTP security header grade/analysis including presence or absence of headers like HSTS, CSP, X-Frame-Options, and similar security signals.
Example use cases
Pre-launch security posture check
“Before we go live, can you audit mycompany.com for DNS resolution, TLS certificate validity, and HTTP security headers so I know if there are any glaring security issues?”
Competitor infrastructure intelligence
“Pull domain OSINT on shopify.com — I want to know their DNS IPs, who issued their SSL cert and when it expires, and how strong their HTTP security headers are.”
Incident response domain investigation
“We got a phishing report pointing to suspicious-domain.net — can you do a quick OSINT check on it including DNS resolution, TLS certificate issuer, and security header grade?”
Technical details
Endpoint
POSThttps://serp-extract.agentdiet.dev/v1/osint?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need quick, live reconnaissance on a domain's DNS resolution, TLS certificate status, and HTTP security posture in a single call. It is ideal for security audits, OSINT investigations, pre-deployment checks, or competitive infrastructure analysis without needing to run separate dig, openssl, or curl commands. Prefer it over manual tooling when an agent needs structured, token-efficient security data about any public domain.
Side effects
- Domain does not exist or fails DNS resolution — returns error or empty DNS result
- Domain has no HTTPS endpoint — TLS certificate data unavailable
- Domain is unreachable or times out — partial or empty response
- Invalid domain input format — returns validation error
- Domain blocks or rate-limits the recon probe — incomplete header data returned
