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://x402-audit.agentdiet.dev/v1/dns-whois-tls-recon)
Output
Returns live DNS resolution results (IPv4 and IPv6 addresses), TLS certificate metadata (issuer, expiry date, validity status), and an HTTP security header analysis with a grade or score, all gathered in real time for the specified domain.
Example use cases
Pre-launch security audit for SaaS
“Before we go live, can you check the DNS resolution, TLS certificate details, and HTTP security headers for app.mystartup.com so I know if there are any obvious security gaps?”
Competitor infrastructure OSINT
“Pull domain OSINT on shopify.com for me — I want the TLS certificate issuer and expiry date, the resolved IPv4 and IPv6 addresses, and the HTTP security header grade.”
Certificate expiry monitoring check
“Can you inspect the TLS certificate on mail.acmecorp.io and tell me when it expires and who issued it, along with whether the security headers are properly set?”
Technical details
Endpoint
POSThttps://x402-audit.agentdiet.dev/v1/dns-whois-tls-recon?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need live, real-time DNS, TLS, and HTTP security data for a specific domain in a single call. It is ideal for security audits, OSINT investigations, certificate expiry checks, and infrastructure reconnaissance without requiring separate DNS, SSL, and security header tools.
Side effects
- Domain does not exist or fails DNS resolution — returns DNS lookup error
- Domain is unreachable or times out — returns connection timeout
- Domain has no HTTPS/TLS configured — TLS fields may be empty or error
- Invalid domain format provided — returns validation error
- Rate limiting or payment failure via x402 — returns HTTP 402
