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://x402broker.com/v1/dns-whois-tls-recon)
Output
Returns live IPv4 and IPv6 DNS resolution results, TLS certificate metadata (issuer, validity dates, expiry), and an HTTP security header audit including presence and grading of headers such as HSTS, CSP, X-Frame-Options, and related security controls for the target domain.
Example use cases
Pre-deployment security audit
“Before we point our domain to the new server, can you check the TLS cert issuer, expiry date, and HTTP security header grade for api.mycompany.com so I know if there are any issues?”
Competitor infrastructure recon
“I'm doing a security analysis of our competitors — can you pull the DNS records, TLS certificate details, and security header posture for shopify.com?”
Certificate expiry monitoring check
“I need to know if the SSL certificate on payments.acmecorp.io is close to expiring — can you look it up and tell me the issuer and expiry date along with any security header issues?”
Technical details
Endpoint
GEThttps://x402broker.com/v1/dns-whois-tls-recon?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a quick, all-in-one live recon of a domain's DNS, TLS certificate, and HTTP security posture in a single call — especially useful for OSINT workflows, security audits, certificate expiry monitoring, or infrastructure reconnaissance on any domain without needing separate DNS, SSL, and header-checking tools.
Side effects
- Domain does not exist or fails DNS resolution — returns error or empty DNS records
- Target domain has no HTTPS/TLS endpoint — TLS fields may be absent or null
- Domain is unreachable or times out during live probe — returns timeout or connection error
- Malformed domain input — returns validation error for invalid domain string
- Domain blocks automated probes — security headers or TLS handshake may fail
