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/cert-transparency)
Output
Returns live IPv4 and IPv6 DNS resolution results, TLS certificate details (issuer, validity period, expiry date), and an HTTP security headers grade for the queried domain.
Example use cases
Pre-acquisition domain security audit
“Before we proceed with this acquisition, can you pull the DNS resolution, TLS certificate issuer and expiry, and HTTP security grade for acmecorp.com so I can assess their security posture?”
Certificate expiry monitoring alert
“Can you check the TLS certificate on payments.mycompany.com and tell me the expiry date and who issued it? I want to know if it's close to expiring.”
Suspicious domain OSINT investigation
“I got a phishing report mentioning secure-login-bankofamerica.xyz — can you run OSINT on it and tell me its DNS records, TLS cert issuer, and security header grade?”
Technical details
Endpoint
GEThttps://x402broker.com/v1/cert-transparency?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a combined, live view of a domain's DNS records, TLS certificate metadata, and HTTP security headers in a single call — particularly for security audits, OSINT investigations, pre-acquisition due diligence, or certificate expiry monitoring. It is preferable over generic whois or passive certificate-transparency log searches when you need live, real-time data across all three dimensions simultaneously.
Side effects
- Domain does not exist or fails DNS resolution — may return empty or error response
- Domain has no TLS certificate (plain HTTP only) — TLS fields may be null or absent
- Connection timeout if the target domain is unreachable or behind a firewall
- Invalid domain format provided — API may return a validation error
- Rate limiting or payment failure due to x402 protocol issues
