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://mcp-compiler.agentdiet.dev/v1/ssl-audit)
Output
Returns live DNS resolution results (IPv4/IPv6 addresses), TLS certificate metadata (issuer, expiry date, validity status), and an HTTP security headers audit/grade for the queried domain.
Example use cases
Pre-vendor security due diligence
“Before we integrate with this SaaS vendor at stripe.com, can you pull their DNS records, TLS certificate details, and HTTP security header grade so I can review their security posture?”
SSL certificate expiry monitoring
“Check the TLS certificate on openai.com and tell me who issued it and when it expires — I want to know if we're at risk of it expiring soon.”
Competitor infrastructure OSINT
“I need a quick OSINT snapshot of github.com — IPv4 and IPv6 addresses, TLS certificate issuer and expiry date, and their HTTP security headers score.”
Technical details
Endpoint
GEThttps://mcp-compiler.agentdiet.dev/v1/ssl-audit?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a combined, live snapshot of a domain's DNS, TLS, and HTTP security posture in a single call — especially for security due diligence, pre-integration vendor checks, certificate expiry monitoring, or domain OSINT investigations. It is preferable to separate DNS or SSL tools when you need all three data layers together without chaining multiple API calls.
Side effects
- Domain does not exist or cannot be resolved — DNS lookup failure returned
- Domain is reachable but has no TLS certificate (HTTP-only) — certificate data absent
- Domain is valid but TLS certificate is expired or self-signed — flagged in response
- Network timeout reaching the target domain — error or partial result returned
- Invalid domain format provided — validation error returned
