Run the SSL Labs TLS assessment for a host and return its full security report

Price: 5 credits

💡 AI Hint: Assess the TLS / SSL configuration of a host (the Qualys SSL Server Test). Returns, per server endpoint (IP), the letter grade (A+ down to F, plus the trust-ignored grade), the supported TLS protocol versions and cipher suites, a full battery of vulnerability checks (Heartbleed, POODLE, FREAK, Logjam, DROWN, BEAST, Bleichenbacher, Ticketbleed, RC4, insecure renegotiation, etc.), HSTS policy, forward secrecy, OCSP stapling, handshake simulations for many client platforms, and the full certificate chain (subject, SANs, issuer, signature & key algorithm, key size, validity dates, fingerprints and PEM). Accepts a bare domain or a URL. Results are returned from a recent cache by default; set start_new to force a fresh live test.

⚠️ Common errors: 412: Host could not be assessed (unable to resolve the domain or no secure endpoint)
