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-whois-tls-recon)
Output
Returns live DNS resolution results (IPv4 and IPv6 addresses), TLS certificate details including issuer and expiration date, and an HTTP security header audit/grade for the queried domain.
Example use cases
Pre-vendor security due diligence
“Before we integrate with this third-party vendor, can you check the domain security posture of acmecorp.com — specifically their TLS certificate validity, who issued it, and whether their HTTP security headers are up to standard?”
SSL certificate expiry monitoring
“Can you check when the TLS certificate for mybusiness.com expires and who issued it? I want to make sure we're not about to have an outage.”
Competitive infrastructure OSINT
“I need a quick recon on competitor.io — pull their DNS records including IPv4 and IPv6 addresses, TLS cert details, and HTTP security grade so I can understand their infrastructure setup.”
Technical details
Endpoint
GEThttps://alpha-stream.agentdiet.dev/v1/dns-whois-tls-recon?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a combined DNS + TLS + HTTP security header snapshot for a domain in a single call, especially for OSINT workflows, security audits, vendor due diligence, or certificate expiry monitoring. It is ideal when you want structured recon data without standing up your own scanning infrastructure.
Side effects
- Domain does not exist or is unresolvable — DNS lookup fails with NXDOMAIN
- Domain has no TLS/HTTPS — certificate data unavailable
- Request times out due to slow DNS or unresponsive target server
- Invalid domain string format provided
- Domain resolves but HTTP server is unreachable for header inspection
