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://shopify-spy.agentdiet.dev/v1/cert-transparency)
Output
Returns live DNS resolution data (IPv4/IPv6 addresses), TLS certificate details (issuer, expiry/validity dates), and an HTTP security headers grade or breakdown for the queried domain, enabling assessment of the domain's security posture.
Example use cases
Pre-launch security posture check
“Before we go live, can you audit the TLS certificate, DNS setup, and HTTP security headers for mybusiness.com so I know if anything looks misconfigured?”
Vendor due diligence domain audit
“I'm evaluating a SaaS vendor — can you check the TLS certificate issuer, expiry, and security header grade for their domain vendor-portal.io?”
Competitor OSINT recon
“Run a quick domain recon on competitor.com — I want to see their IPv4 and IPv6 DNS records, who issued their SSL cert, when it expires, and how they score on HTTP security headers.”
Technical details
Endpoint
GEThttps://shopify-spy.agentdiet.dev/v1/cert-transparency?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a combined, live snapshot of a domain's DNS resolution, TLS certificate health, and HTTP security posture in a single call — ideal for security audits, vendor due diligence, OSINT research, or monitoring certificate expiry. Prefer this over manual tools when automation or agent-driven workflows require structured output.
Side effects
- Domain does not exist or fails DNS resolution — returns empty or error response
- TLS handshake failure if the target server is unreachable or refuses connections
- Invalid domain input format — may return validation error
- Domain with no HTTPS — TLS certificate data unavailable
- Rate limiting or payment failure if x402 payment is not processed correctly
