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/subdomain-scan)
Output
Returns live IPv4 and IPv6 DNS resolution results, TLS certificate issuer and expiry date, and an HTTP security header grade for the queried domain.
Example use cases
Pre-deployment TLS certificate check
“Before we launch, can you check that api.mycompany.com has a valid TLS certificate, who issued it, and when it's set to expire?”
Security audit for third-party vendor domain
“I need to vet a vendor — can you pull the DNS resolution, TLS cert issuer and expiry, and HTTP security grade for vendor-portal.supplierxyz.com?”
Monitoring competitor domain security posture
“Can you do a quick security recon on competitor.io — I want to know their IPv4/IPv6 DNS, TLS certificate details, and how their HTTP security headers score?”
Technical details
Endpoint
GEThttps://x402broker.com/v1/subdomain-scan?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a fast, lightweight OSINT snapshot of a domain's DNS health, TLS certificate validity, and HTTP security posture without running a full penetration test. Ideal for pre-launch checks, vendor vetting, or routine security hygiene on a single domain.
Side effects
- Domain does not resolve — DNS lookup failure returned
- Domain has no TLS certificate — certificate data absent or error
- HTTP security headers not accessible — connection refused or timeout
- Invalid domain input — malformed domain string
- Rate limit or payment failure — 402 response if USDC payment not processed
