Live TLS/SSL certificate health check for any hostname. Catches expiry, hostname mismatch, untrusted chains and weak protocols before you trust the endpoint.
Free: GET /run?target=example.com — expiry, issuer, hostname match, verdict.
Deep (paid): GET /pro/run?target=example.com — negotiated protocol/cipher strength, full chain-trust walk, per-finding fixes. Pay with a card via /pro/checkout or per-call USDC (x402) on Base.
