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://cve-intel.agentdiet.dev/v1/dns-recon)
Output
Returns live DNS resolution results including IPv4 and IPv6 addresses, TLS certificate metadata (issuer, expiry date), and an HTTP security header grade/assessment for the queried domain
Example use cases
Pre-launch security audit for new site
“We're about to launch our new site at mycompany.com — can you check its DNS resolution, verify the TLS certificate issuer and expiry date, and tell me how the HTTP security headers grade?”
Investigating a suspicious phishing domain
“I got a suspicious email from notifications-update.io — can you pull the DNS records, check the TLS certificate details, and audit the security headers to help me assess if this domain is legit?”
Monitoring competitor infrastructure
“Can you do a recon on openai.com — show me its resolved IP addresses, TLS certificate issuer and expiry, and the HTTP security header grade?”
Technical details
Endpoint
GEThttps://cve-intel.agentdiet.dev/v1/dns-recon?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a quick, all-in-one OSINT snapshot of a domain's DNS, TLS certificate, and HTTP security posture without having to chain multiple tools. Ideal for security researchers, threat analysts, or DevOps engineers checking domain health, certificate validity, or investigating suspicious domains. Prefer this over general-purpose DNS lookup tools when you also need TLS and security header data in a single call.
Side effects
- Domain does not exist or cannot be resolved — returns DNS lookup failure
- TLS certificate missing or self-signed — incomplete certificate data returned
- Domain is unreachable or times out — partial or empty response
- Invalid domain format supplied — validation error on input
- HTTP security headers unavailable if domain blocks HTTP probes
