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://shopify-intel.agentdiet.dev/v1/asn-lookup)
Output
Returns live DNS resolution results including IPv4 and IPv6 addresses, TLS certificate metadata (issuer, expiry date, validity status), and an HTTP security grade reflecting the presence and quality of security headers such as HSTS, CSP, X-Frame-Options, and others.
Example use cases
Vendor security due diligence
“We're about to sign a contract with a new SaaS vendor at vendorsuite.io — can you check their domain's TLS certificate validity, who issued it, and whether they have proper HTTP security headers in place?”
Competitor infrastructure recon
“I want to know the DNS setup, SSL certificate details, and security header grade for our competitor's domain, rivalapp.com — pull the full OSINT picture for me.”
Pre-launch site security audit
“Before we go live, can you check our domain newproduct.example.com for DNS resolution, TLS certificate expiry, and HTTP security headers so we know if anything is misconfigured?”
Technical details
Endpoint
GEThttps://shopify-intel.agentdiet.dev/v1/asn-lookup?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a quick, live OSINT snapshot of a domain's network and security posture — specifically DNS resolution, TLS certificate health, and HTTP security header grades — without setting up your own scanning infrastructure. Ideal for security due diligence, vendor assessments, competitive reconnaissance, or pre-deployment audits where a single-call, pay-per-use model is preferable to running your own tools.
Side effects
- Domain does not exist or fails DNS resolution — returns empty or error for DNS fields
- Domain has no HTTPS endpoint — TLS certificate fields unavailable
- Target domain blocks or rate-limits the probe — incomplete or timeout response
- Malformed domain input — validation error returned
- Domain resolves but has no security headers — security grade reflects absence
