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://cve-intel.agentdiet.dev/v1/osint)
Output
Returns live DNS resolution data (IPv4 and IPv6 addresses), TLS certificate metadata (issuer, expiry date, validity status), and an HTTP security header grade reflecting the presence or absence of headers like HSTS, CSP, X-Frame-Options, and similar security controls.
Example use cases
Pre-acquisition domain security audit
“Before we finalize this vendor deal, can you pull the DNS records, TLS certificate details, and security header grade for acmecorp.com so I can assess their web security posture?”
SSL certificate expiry monitoring
“Check when the TLS certificate for example.com expires and who issued it — I want to know if we're at risk of an upcoming outage.”
Competitor infrastructure reconnaissance
“Do a quick OSINT sweep on openai.com — I want their IPv4/IPv6 addresses, TLS certificate issuer, and how they score on HTTP security headers.”
Technical details
Endpoint
GEThttps://cve-intel.agentdiet.dev/v1/osint?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need live, real-time DNS, TLS, and HTTP security intelligence for a specific domain in a single call — especially useful for security audits, vendor assessments, or OSINT investigations where you need certificate expiry, issuer chain, IPv4/IPv6 resolution, and security header grading without assembling multiple separate tools.
Side effects
- Invalid or non-existent domain returns an error or empty DNS resolution
- Domain with no HTTPS returns missing TLS certificate data
- Rate limiting or payment failure returns HTTP 402
- Timeout if target domain is slow to respond
- Malformed domain string causes validation error
