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://github-audit.agentdiet.dev/v1/tls-scanner)
Output
Returns live DNS resolution data (IPv4 and IPv6 addresses), TLS certificate details including issuer and expiry date, and an HTTP security header grade reflecting the domain's security posture.
Example use cases
Pre-launch security check for new domain
“We're about to launch our product at newstartup.io — can you scan that domain and tell me if the TLS cert is valid, who issued it, when it expires, and whether our security headers are in good shape?”
Vendor due diligence OSINT
“I need to vet a third-party vendor before we integrate with them — can you pull the DNS records, TLS certificate info, and HTTP security grade for vendorcompany.com so I know what we're dealing with?”
Monitor competitor infrastructure
“Can you run a quick domain recon on competitor.com and tell me their DNS IPs, TLS certificate issuer and expiry, and how well their security headers are configured?”
Technical details
Endpoint
GEThttps://github-audit.agentdiet.dev/v1/tls-scanner?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a quick, live OSINT snapshot of a domain's DNS infrastructure, TLS certificate health, and HTTP security configuration in a single call — especially useful for vendor due diligence, pre-launch security checks, or competitive infrastructure reconnaissance. Prefer this over manual tools or general web scrapers when you need structured, machine-readable security data at low cost ($0.01/call).
Side effects
- Domain does not exist or fails to resolve — returns DNS error
- Domain has no TLS certificate — TLS fields may be empty or flagged
- Network timeout reaching the target domain — request may fail
- Invalid or malformed domain input — returns validation error
- Domain actively blocks external scanners — may return incomplete data
