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/asn-lookup)
Output
Returns live IPv4 and IPv6 DNS resolution results, TLS certificate details (issuer, expiry date, validity), and an HTTP security headers assessment including a security grade — giving a comprehensive snapshot of a domain's public infrastructure security posture.
Example use cases
Security audit before vendor onboarding
“Before we integrate with acmecorp.com, can you check their domain's TLS certificate issuer and expiry, IPv4/IPv6 DNS records, and give me a security header grade so I can assess their infrastructure posture?”
Phishing domain investigation
“I got a suspicious email from paypa1-secure.com — can you do a full DNS and TLS cert recon on that domain to see who issued the certificate, when it expires, and what their HTTP security headers look like?”
Monitor competitor infrastructure
“Run a domain OSINT check on stripe.com and tell me their TLS cert details, DNS resolution, and HTTP security grade — I want to benchmark our own setup against theirs.”
Technical details
Endpoint
GEThttps://cve-intel.agentdiet.dev/v1/asn-lookup?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a quick, all-in-one passive recon snapshot of a domain's DNS, TLS, and HTTP security posture without deploying your own scanning infrastructure. Ideal for security researchers, threat analysts, or onboarding workflows needing to vet external domains cheaply at $0.01 per call.
Side effects
- Domain does not exist or fails DNS resolution — returns error or empty DNS fields
- Domain has no HTTPS endpoint — TLS certificate fields may be absent or null
- Rate limiting or upstream timeout for live probes — may return partial data or error
- Invalid domain format provided — returns validation error
- Domain is behind a CDN or load balancer obscuring true origin TLS details
