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://github-audit.agentdiet.dev/v1/dns-recon)
Output
Returns live DNS resolution results (IPv4 and IPv6 addresses), TLS certificate details (issuer, expiry date, validity), and an HTTP security header grade or analysis for the target domain, enabling a complete security and infrastructure snapshot.
Example use cases
Vendor security due diligence check
“Before we sign a contract with acmecorp.com, can you check their DNS resolution, TLS certificate issuer and expiry, and HTTP security headers grade so I can assess their security posture?”
Monitor SSL cert expiry for own domain
“Can you inspect the TLS certificate for mybusiness.com and tell me who issued it and when it expires so I can make sure we don't get caught off guard by an expiration?”
Competitive OSINT on a rival's infrastructure
“Run an OSINT recon on competitor.io — I want their IPv4 and IPv6 DNS records, TLS certificate details, and HTTP security header grade to understand their infrastructure setup.”
Technical details
Endpoint
GEThttps://github-audit.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 live DNS resolution, TLS certificate health, and HTTP security posture without running separate tools. It is ideal for security due diligence, vendor assessments, competitive intelligence, or monitoring your own infrastructure's certificate expiry and header configuration.
Side effects
- Domain does not exist or fails DNS resolution — returns error or empty DNS records
- Domain has no TLS certificate (HTTP only) — TLS fields may be null or absent
- Target domain blocks probes or returns connection timeouts — partial results or timeout error
- Malformed domain input — validation error indicating invalid domain format
- Transient network error reaching the target — may return incomplete data
