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://alpha-stream.agentdiet.dev/v1/tls-scanner)
Output
Returns live DNS resolution results (IPv4 and IPv6 addresses), TLS certificate details (issuer, expiry date, validity), and an HTTP security header grade/assessment for the queried domain.
Example use cases
Pre-launch security audit
“Before we go live, can you check our domain startup-app.com for its TLS certificate issuer and expiry, see what IPs it resolves to, and grade its HTTP security headers?”
Vendor domain due diligence
“I'm about to integrate with a third-party vendor at vendor-api.io — can you pull their DNS records, check if their TLS cert is valid and who issued it, and tell me how their security headers look?”
Certificate expiry monitoring
“Can you check payments.mystore.com to see if the TLS certificate is close to expiring and what its current issuer is?”
Technical details
Endpoint
GEThttps://alpha-stream.agentdiet.dev/v1/tls-scanner?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a quick, unified OSINT snapshot of a domain's DNS, TLS, and HTTP security posture in a single call. Prefer it over manual DNS lookups or separate SSL checkers when you want all three dimensions — IP resolution, certificate metadata, and security header grading — in one response, especially for due diligence, vendor risk assessment, or pre-deployment security checks.
Side effects
- Domain does not exist or fails DNS resolution — empty or error response
- Domain is unreachable or times out — timeout error
- Invalid or malformed domain input — validation error
- Domain has no HTTPS/TLS — certificate fields may be null or absent
- HTTP security headers absent — grade may reflect missing headers
