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://workflows.agentdiet.dev/v1/asn-lookup)
Output
Returns live DNS resolution results including IPv4 and IPv6 addresses, TLS certificate metadata (issuer, expiry date, validity), and an HTTP security header grade or assessment for the queried domain
Example use cases
Pre-launch domain security audit
“Before we go live with our new product, can you check that our domain newproduct.io has proper TLS cert coverage, resolves correctly on both IPv4 and IPv6, and passes HTTP security header checks?”
Third-party vendor risk assessment
“I need to assess the security posture of a vendor we're considering — can you pull the DNS records, TLS certificate details, and HTTP security grade for vendorportal.com?”
Certificate expiry monitoring check
“Can you check stripe.com's TLS certificate right now and tell me who issued it and when it expires so I know if it's at risk of lapsing soon?”
Technical details
Endpoint
GEThttps://workflows.agentdiet.dev/v1/asn-lookup?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a combined DNS, TLS, and HTTP security posture snapshot for a domain in a single call, particularly useful for OSINT workflows, vendor risk assessments, certificate expiry monitoring, or pre-launch security audits where live data is required
Side effects
- Domain does not exist or fails DNS resolution — no records returned
- Domain is unreachable or times out during TLS handshake — certificate data unavailable
- Domain does not serve HTTPS — TLS certificate inspection fails
- Invalid or empty domain input — request rejected with validation error
- Payment not completed — HTTP 402 returned blocking the response
