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://token-intel.agentdiet.dev/v1/tls-scanner)
Output
Returns live DNS resolution results (IPv4 and IPv6 addresses), TLS certificate metadata (issuer, subject, expiry date, validity status), and an HTTP security header analysis including presence and grading of headers such as HSTS, CSP, X-Frame-Options, and overall security grade.
Example use cases
Pre-launch security audit for new site
“Before we go live, can you scan our domain newproduct.io and tell me its TLS certificate issuer, expiry date, and whether our HTTP security headers like HSTS and CSP are properly configured?”
Vendor due diligence on third-party API
“We're evaluating a third-party vendor at api.vendorcorp.com — can you check their DNS resolution, TLS certificate validity, and security header grade so I can include it in our risk assessment?”
Monitor competitor domain TLS posture
“Pull the TLS certificate details and HTTP security grade for competitor.com — I want to know their cert issuer, when it expires, and what IPv4 and IPv6 addresses they're resolving to right now.”
Technical details
Endpoint
GEThttps://token-intel.agentdiet.dev/v1/tls-scanner?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a fast, single-call OSINT snapshot of a domain's DNS posture, TLS certificate health, and HTTP security header configuration without setting up local tooling like nmap, openssl, or securityheaders.com. Prefer it for automated recon pipelines, vendor risk assessments, or pre-launch security checklists where live certificate and DNS data is required.
Side effects
- Domain does not exist or fails DNS resolution — no results returned
- Domain is unreachable or times out during TLS handshake
- Domain has no TLS certificate (HTTP-only) — certificate fields may be empty
- Invalid or malformed domain input — validation error returned
- Target blocks automated scanning — connection refused or incomplete response
