How this service works
Inspect a public HTTPS hostname's TLS certificate and observable response security headers without active scanning.
Output
Returns point-in-time evidence of the target hostname's TLS certificate (issuer, validity dates, subject, cipher info) and observable HTTP response security headers (e.g. HSTS, CSP, X-Frame-Options, X-Content-Type-Options), all collected passively without active scanning.
Example use cases
Vendor security due diligence check
“I need to verify the TLS setup and security response headers for payments.acme.com before we integrate with them — can you pull a snapshot of their certificate and observable security headers?”
Pre-launch HTTPS compliance audit
“We're about to launch myapp.example.com — can you check its TLS certificate validity and what security headers it's serving so I can confirm everything looks right before we go live?”
Competitive security posture comparison
“Can you grab the TLS certificate info and security headers from competitor.io so I can see what HSTS, CSP, and other security headers they have in place?”
Technical details
Endpoint
GEThttps://phases-prot-shine-royal.trycloudflare.com/x402/tls-securityWhen to prefer
Choose this endpoint when you need a passive, non-intrusive read of a public HTTPS domain's TLS certificate properties and security response headers without triggering active scans or port sweeps. Ideal for due diligence, compliance snapshots, or pre-integration security checks where you want structured evidence without touching the target aggressively. Prefer this over general website analysis tools when TLS and security header specifics are the primary concern.
Side effects
- Domain does not exist or is unreachable — returns error indicating hostname could not be resolved
- Hostname uses HTTP only (no HTTPS) — endpoint may return empty or error response
- Certificate is self-signed or expired — data returned but may flag anomalies
- Cloudflare or CDN shields actual origin headers — results reflect edge, not origin
- Rate limiting or network timeout on the target host — returns partial or error result
- Invalid domain format provided — schema validation error
