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-spy.agentdiet.dev/v1/asn-lookup)
Output
Returns live DNS resolution data (IPv4 and IPv6 addresses), TLS certificate details (issuer, expiry date), and an HTTP security headers grade for the queried domain, enabling assessment of infrastructure and security posture.
Example use cases
Vendor security due diligence check
“Before we integrate with this payment processor, can you pull the TLS certificate info, DNS records, and HTTP security grade for checkout.acme-payments.com so I can assess their security posture?”
Competitor infrastructure reconnaissance
“I want to do some OSINT on our main competitor — can you check the DNS resolution, TLS cert issuer and expiry, and security headers grade for shopify.com?”
Monitor certificate expiry before renewal deadline
“Can you inspect the TLS certificate on our staging site staging.mycompany.io and tell me who issued it, when it expires, and whether our security headers are properly configured?”
Technical details
Endpoint
GEThttps://shopify-spy.agentdiet.dev/v1/asn-lookup?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a quick, combined OSINT snapshot of a domain's DNS, TLS certificate, and HTTP security configuration in a single call — ideal for security due diligence, vendor assessments, competitive reconnaissance, or certificate expiry monitoring without needing to chain multiple DNS/TLS/header tools.
Side effects
- Domain does not exist or fails DNS resolution — empty or error response
- TLS handshake fails if domain has no HTTPS endpoint
- Invalid domain format passed — validation error
- Target domain blocks or throttles automated probes — incomplete results
- Network timeout if domain has slow DNS or TLS response
