  • check_certificate

    Run a live TLS handshake against host:port and audit the certificate the server presents. Returns an A/B/C/F grade and summary, expiry (days remaining), hostname match, chain completeness and trust against Mozilla's root store, negotiated TLS version and cipher suite, key type/size, findings, and a link to the full report. Revocation (OCSP/CRL) is NOT checked. Hosts on Cloudflare's own network cannot be checked live (result: isError with code live_check_unavailable, no grade); a failed handshake returns check_failed with no grade. Read-only: it only opens a TLS connection to the public host. Same engine, cache and limits as the CertGuard JSON API (GET /api/v1/check).
