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 results (IPv4/IPv6 addresses), TLS certificate metadata including issuer and expiry date, and an HTTP security headers assessment/grade for the target domain.
Example use cases
Pre-acquisition domain security audit
“We're about to acquire a startup — can you run a domain recon on theirstartup.com and tell me who issued their TLS certificate, when it expires, what IPs it resolves to, and whether their HTTP security headers are any good?”
Certificate expiry monitoring alert
“Check the TLS certificate on api.mycompany.com — I need to know the issuer and exact expiry date so I can tell if we're at risk of it expiring soon.”
Competitor infrastructure recon
“Do a quick OSINT sweep on competitor.io — pull the live IPv4 and IPv6 DNS records, TLS certificate details, and their HTTP security header grade.”

Endpoint
POSThttps://cve-intel.agentdiet.dev/v1/osint?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a unified single-call recon on a domain's DNS posture, TLS certificate health, and HTTP security headers — especially in security audits, pre-acquisition due diligence, certificate expiry monitoring, or threat-intelligence workflows where live data is required rather than cached records.
Side effects
- Domain does not exist or fails to resolve — returns DNS resolution error
- Domain is unreachable or times out during live probing
- TLS certificate is absent or self-signed and cannot be fully parsed
- HTTP endpoint returns non-standard response preventing header grading
- Invalid domain format provided in request body
