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/osint)
Output
Returns live DNS resolution results including IPv4 and IPv6 addresses, TLS certificate information (issuer, validity dates, expiry), and an HTTP security headers analysis with a security grade for the queried domain.
Example use cases
Pre-launch security audit
“Before we go live, can you check openai.com's TLS certificate — who issued it, when it expires — and tell me whether the HTTP security headers are up to scratch?”
Vendor due diligence check
“I'm evaluating a third-party vendor at payments.acme.io — can you pull their DNS records, check their TLS certificate details, and grade their HTTP security headers so I know if they meet our baseline?”
Expiring certificate alert investigation
“We got an alert that one of our partner domains might have an expiring cert — can you run an OSINT recon on partnerportal.example.com and tell me the TLS expiry date and issuer?”
Technical details
Endpoint
GEThttps://whale-momentum.agentdiet.dev/v1/osint?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a combined, live OSINT snapshot of a domain's DNS resolution, TLS certificate status, and HTTP security posture in a single call. Prefer it over manual DNS lookup tools or separate certificate checkers when you need all three data points together, especially for security audits, vendor due diligence, or monitoring certificate expiry.
Side effects
- Domain does not resolve — DNS lookup fails, no IP addresses returned
- Domain unreachable — TLS handshake cannot be completed, certificate details unavailable
- Invalid domain input — malformed or empty domain name returns a validation error
- Domain has no HTTPS — security headers and TLS data cannot be retrieved
- Rate limit exceeded — too many calls in a short window
- Payment failure — x402 payment not processed, endpoint returns 402
