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://alpha-stream.agentdiet.dev/v1/dns-recon)
Output
Returns live DNS resolution results including IPv4 and IPv6 addresses, TLS certificate details (issuer, expiry date, validity), and an HTTP security header grade or analysis indicating which security headers (e.g. HSTS, CSP, X-Frame-Options) are present or missing.
Example use cases
Pre-launch security audit for new domain
“Before we go live, can you check anthropic.com for its DNS resolution, TLS certificate details, and HTTP security header grade so I know if anything needs fixing?”
Monitor competitor domain security posture
“Do a quick OSINT recon on openai.com — I want to know their DNS IPs, who issued their TLS cert and when it expires, and whether their security headers are solid.”
Investigate suspicious domain during incident response
“We've got a domain in our logs that looks suspicious — can you run a full DNS and TLS certificate inspection on malicious-lookalike.com so I can see what's behind it?”
Technical details
Endpoint
GEThttps://alpha-stream.agentdiet.dev/v1/dns-recon?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a combined, single-call lookup of DNS records, TLS certificate metadata, and HTTP security headers for a domain. It is ideal for security OSINT workflows, pre-launch audits, incident response triage, or monitoring competitor security posture, especially when you want all three signals (DNS, TLS, headers) in one call rather than querying separate tools.
Side effects
- Domain does not exist or fails DNS resolution — may return empty or error response
- Domain is unreachable over HTTPS — TLS inspection will fail
- Firewall or geo-blocking prevents connection — partial results
- Invalid domain format supplied — validation error
- TLS certificate is self-signed or expired — may affect grading accuracy
