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://onchain-risk.agentdiet.dev/v1/dns-whois-tls-recon)
Output
Returns live DNS resolution results including IPv4/IPv6 addresses, TLS certificate details such as issuer and expiration date, and an HTTP security headers grade reflecting the domain's security configuration.
Example use cases
Pre-launch security posture check
“Before we go live, can you check the DNS resolution, TLS certificate issuer and expiry, and HTTP security headers grade for ourstartup.com so I know if anything is misconfigured?”
Vendor domain trust verification
“I need to verify the security posture of a vendor we're about to integrate with — can you pull the DNS records, SSL certificate details, and security header grade for theircompany.io?”
Competitor domain OSINT sweep
“Can you do a full domain recon on competitor.com? I want to see their IPv4 and IPv6 addresses, who issued their TLS cert, when it expires, and how their HTTP security headers score.”
Technical details
Endpoint
GEThttps://onchain-risk.agentdiet.dev/v1/dns-whois-tls-recon?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need live, real-time OSINT on a specific domain covering DNS, TLS, and HTTP security in a single call. Prefer it over generic WHOIS tools when you also need TLS certificate issuer/expiry and HTTP security header grading together. Best for security audits, vendor due diligence, competitive intelligence, or pre-deployment checks.
Side effects
- Domain does not exist or fails DNS resolution — returns error or empty DNS records
- TLS certificate missing or expired — may return null cert fields or error state
- Domain blocks HTTP probes — security header grade may be unavailable
- Invalid domain input (e.g. malformed string) — returns validation error
- Network timeout reaching the target domain — returns timeout error
