One-shot health probe for any endpoint: HTTP status and latency, TLS certificate issuer and days-to-expiry, response size, security-header audit (HSTS, CSP, X-Content-Type-Options, X-Frame-Options) and named issues (SLOW_RESPONSE, CERTIFICATE_EXPIRING, SERVER_ERROR_STATUS). Call it on a schedule and you have uptime monitoring for a fraction of a cent.
