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://whale-momentum.agentdiet.dev/v1/dns-recon)
Output
Returns live DNS resolution results (IPv4/IPv6 addresses), TLS certificate details including issuer and expiry date, and an HTTP security headers analysis with a security grade for the target domain.
Example use cases
Pre-launch SSL expiry check
“Check the TLS certificate for mycompany.com — specifically who issued it and when it expires, so I know if we need to renew soon.”
Competitor security posture audit
“Run a DNS and security headers recon on stripe.com — I want to know what IPs it resolves to, the cert details, and how their HTTP security grade looks.”
Incident investigation on suspicious domain
“I need full OSINT on the domain phishing-suspect.net — give me its DNS resolution, TLS certificate issuer and expiry, and any HTTP security header red flags.”
Technical details
Endpoint
GEThttps://whale-momentum.agentdiet.dev/v1/dns-recon?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a single-call, live snapshot of a domain's DNS resolution, TLS certificate validity, and HTTP security posture without setting up your own tooling. Ideal for security audits, certificate expiry monitoring, OSINT investigations, or infrastructure verification tasks.
Side effects
- Domain does not exist or fails DNS resolution — returns empty or error response
- Domain has no TLS certificate (HTTP-only) — TLS fields will be null or absent
- Domain times out during live inspection — may return partial data or timeout error
- Invalid domain format provided — returns validation error
- Domain is unreachable from the probe host — connection refused or network error
