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://company-enrich.agentdiet.dev/v1/ssl-audit)
Output
Returns live DNS resolution results (IPv4 and IPv6 addresses), TLS certificate metadata (issuer, expiry date, validity status), and an HTTP security header grade/assessment for the queried domain.
Example use cases
Vendor security due diligence check
“Before we integrate with this new payment vendor, can you audit paymentco.io — check their DNS resolution, who issued their TLS cert, when it expires, and how their HTTP security headers score?”
Monitoring competitor domain security
“Pull up the TLS certificate details and HTTP security grade for shopify.com — I want to see the issuer, expiry date, and whether their DNS resolves over both IPv4 and IPv6.”
Pre-launch SSL compliance check
“We're about to go live — can you check mybrand-staging.com for DNS resolution, TLS certificate validity, and security header grade so I can confirm everything's in order before launch?”
Technical details
Endpoint
GEThttps://company-enrich.agentdiet.dev/v1/ssl-audit?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a quick, combined OSINT snapshot of a domain's DNS configuration, TLS certificate health, and HTTP security posture in a single call. Ideal for security due diligence, pre-launch compliance checks, or threat intelligence workflows where DNS + TLS + headers are all needed together rather than querying separate specialized tools.
Side effects
- Domain does not exist or fails DNS resolution — returns error or empty DNS records
- TLS certificate is absent or expired — returns certificate error or null cert fields
- Domain blocks probing — may return incomplete or timed-out security header results
- Invalid domain format provided — returns validation error
