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://token-intel.agentdiet.dev/v1/ssl-audit)
Output
Returns live DNS resolution results (IPv4 and IPv6 addresses), TLS certificate details (issuer organization, validity dates, expiry), and an HTTP security headers grade/analysis indicating presence of headers like HSTS, CSP, X-Frame-Options, etc.
Example use cases
Pre-vendor security due diligence
“Before we integrate with this third-party vendor, can you check their domain payments.acme-vendor.com — I need to know if their SSL cert is valid and who issued it, what their DNS resolves to, and whether they have proper security headers in place?”
Monitor expiring TLS certificates
“Can you check the TLS certificate on api.mycompany.io and tell me who issued it and exactly when it expires? I want to make sure we don't get caught off guard by an expiry.”
Competitor security posture research
“I'm doing an OSINT report on a competitor — can you pull the DNS records, TLS cert details, and HTTP security header grade for shopify.com?”
Technical details
Endpoint
GEThttps://token-intel.agentdiet.dev/v1/ssl-audit?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a quick, live, single-call OSINT snapshot of a domain's DNS, TLS, and HTTP security posture without setting up your own scanner. Ideal for due diligence on third-party vendors, security audits, certificate expiry checks, or enriching domain intelligence in an automated pipeline. Prefer this over manual tools like SSL Labs or dig when you need machine-readable output in an agent workflow at low cost ($0.01/call).
Side effects
- Domain does not exist or fails DNS resolution — returns an error or empty DNS records
- Domain has no TLS certificate (HTTP-only) — TLS fields will be absent or null
- Firewall or CDN blocks the probe — may return incomplete or timeout results
- Invalid domain string provided — returns validation error
- Network timeout reaching the target domain — partial results or error response
