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/ssl-audit)
Output
Returns live DNS resolution results (IPv4/IPv6 addresses), TLS certificate details including issuer and expiry date, and an HTTP security headers grade reflecting the domain's security posture.
Example use cases
Pre-deployment security check
“Before we go live, can you audit the TLS certificate and HTTP security headers on api.mycompany.com and tell me if there are any issues I should know about?”
Vendor due diligence OSINT
“I need to vet a third-party vendor — can you pull the DNS resolution, TLS cert issuer and expiry, and security headers grade for payments.vendorxyz.com?”
Expired certificate monitoring
“Check whether the SSL certificate on legacy.clientportal.io is still valid and when it expires — I think it might have lapsed.”
Technical details
Endpoint
GEThttps://x402broker.com/v1/ssl-audit?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a quick, all-in-one OSINT snapshot of a domain's DNS resolution, TLS certificate health, and HTTP security headers without setting up your own scanning infrastructure. It is ideal for security audits, vendor due diligence, pre-deployment checks, or monitoring third-party domains for certificate expiry. Prefer it over generic whois tools when you specifically need live TLS and security header data in a single call.
Side effects
- Domain does not exist or cannot be resolved — DNS lookup failure returned
- Domain is reachable but does not serve HTTPS — TLS certificate data unavailable
- Request missing required 'domain' query parameter — validation error
- Target server times out during connection — timeout error returned
- Invalid domain format provided — input validation error
