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://company-enrich.agentdiet.dev/v1/tls-scanner)
Output
Returns live DNS resolution results (IPv4 and IPv6 addresses), TLS certificate metadata (issuer, expiry date, validity status), and an HTTP security headers grade reflecting the domain's security posture.
Example use cases
Pre-acquisition domain security audit
“We're considering acquiring a startup — can you check their domain startupco.io for DNS resolution, TLS certificate details like issuer and expiry date, and overall HTTP security header grade?”
Certificate expiry monitoring alert
“Check stripe.com's TLS certificate right now and tell me when it expires and who issued it — I need to know if we're close to any renewal deadline.”
Competitive security posture research
“I'm doing OSINT on our competitor's infrastructure — can you scan competitor.com and report back on their IPv4/IPv6 DNS setup, TLS certificate issuer, and HTTP security headers grade?”
Technical details
Endpoint
GEThttps://company-enrich.agentdiet.dev/v1/tls-scanner?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a live, combined snapshot of a domain's DNS resolution, TLS certificate health, and HTTP security configuration in a single call. It is ideal for security audits, OSINT research, pre-acquisition due diligence, certificate expiry monitoring, or competitive infrastructure reconnaissance — especially when you need all three signal types (DNS, TLS, HTTP headers) together rather than querying separate tools.
Side effects
- Domain does not exist or fails DNS resolution — returns error or empty DNS fields
- Domain has no TLS certificate (HTTP-only) — TLS fields may be null or error
- Firewall or rate limiting on target domain blocks TLS handshake
- Malformed or empty domain input — validation error
- Target domain times out during live probe
