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://company-enrich.agentdiet.dev/v1/dns-whois-tls-recon)
Output
Returns live DNS resolution data including IPv4 and IPv6 addresses, TLS certificate details (issuer, validity dates, expiry), and an HTTP security headers assessment with a security grade for the target domain.
Example use cases
Vendor security due diligence check
“Before we integrate with this new payments vendor, can you pull the DNS resolution, TLS certificate issuer and expiry, and HTTP security header grade for paymentsprovider.io so I can review their security posture?”
SSL certificate expiry monitoring
“Can you check the TLS certificate details for mybusiness.com — specifically who issued it and when it's set to expire? I want to make sure we're not about to go down because of an expired cert.”
Competitor domain OSINT
“Run a quick OSINT recon on competitor.com — I want to know what IPs it resolves to, the details of its SSL certificate, and whether its HTTP security headers are properly configured.”
Technical details
Endpoint
GEThttps://company-enrich.agentdiet.dev/v1/dns-whois-tls-recon?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a quick, all-in-one passive OSINT snapshot of a domain's DNS resolution, TLS certificate health, and HTTP security posture without running separate tools. Ideal for security due diligence, pre-integration vendor checks, certificate expiry monitoring, or competitive reconnaissance where a single $0.01 call yields DNS, TLS, and header data together.
Side effects
- Domain does not exist or fails to resolve — DNS lookup returns empty or error
- Domain has no HTTPS/TLS — certificate data unavailable
- Target server blocks or rate-limits the probe — incomplete security header data
- Invalid domain format supplied — request rejected with validation error
- Transient network timeout reaching the target domain
