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-intel.agentdiet.dev/v1/ssl-audit)
Output
Returns live DNS resolution results (IPv4 and IPv6 addresses), TLS certificate metadata (issuer, expiry date, validity), and an HTTP security header assessment including which security headers are present and an overall security grade for the domain.
Example use cases
Pre-launch security posture check
“Before we go live, can you audit mycompany.com for its TLS certificate details, DNS resolution, and HTTP security header grade so I can see if there are any gaps?”
Competitor security reconnaissance
“I want to understand openai.com's security setup — can you pull their TLS certificate issuer and expiry, DNS records, and HTTP security headers?”
Certificate expiry monitoring alert
“Can you check whether the SSL certificate on stripe.com is close to expiring and who issued it, along with their current security headers?”
Technical details
Endpoint
GEThttps://shopify-intel.agentdiet.dev/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, TLS, and HTTP security posture without setting up separate tooling. It is ideal for security audits, competitive reconnaissance, pre-launch checks, or certificate expiry monitoring where you want live data in a single call rather than stitching together separate DNS, SSL, and header-inspection tools.
Side effects
- Domain does not exist or fails DNS resolution — empty or error response
- Domain is reachable but has no TLS certificate (HTTP-only) — TLS fields absent or null
- Firewall or rate limiting blocks the probe — timeout or 4xx error
- Malformed domain input — validation error returned
- TLS handshake failure — certificate details may be partially unavailable
