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://domain-osint.agentdiet.dev/v1/ssl-audit)
Output
Returns live DNS resolution results (IPv4 and IPv6 addresses), TLS certificate metadata (issuer, validity period, expiry date), and an HTTP security headers grade or breakdown — giving a full picture of a domain's infrastructure and security posture.
Example use cases
Vendor security due diligence check
“Before we integrate with this vendor, can you check the TLS certificate issuer and expiry, IPv4/IPv6 DNS resolution, and security headers grade for their domain api.acmecorp.io?”
SSL expiry monitoring alert
“Check domain-osint.agentdiet.dev right now — I need to know if their SSL certificate is about to expire and who issued it.”
Competitive web security benchmark
“Run a security recon on shopify.com — I want to see their DNS resolution, TLS certificate details, and how their HTTP security headers stack up.”
Technical details
Endpoint
GEThttps://domain-osint.agentdiet.dev/v1/ssl-audit?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a combined, single-call OSINT snapshot covering DNS resolution, TLS certificate metadata, and HTTP security headers for any domain — especially useful for vendor due diligence, continuous security monitoring, competitive benchmarking, or pre-integration security checks where all three data points are needed together rather than calling separate specialized tools.
Side effects
- Domain does not exist or fails to resolve — DNS lookup returns empty or NXDOMAIN
- Domain has no TLS certificate (HTTP-only) — certificate fields may be null or absent
- Security headers not present — grading reflects missing headers
- Network timeout reaching the target domain — connection error returned
- Invalid domain format supplied — validation error on the domain parameter
- Payment not completed — HTTP 402 returned if x402 micropayment not sent
