One-shot health probe for any endpoint: HTTP status and latency, TLS certificate issuer an
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.

"description": "Endpoint monitoring built for agents that watch services — their own, or the APIs they depend on. One call performs a full health probe: HTTP status and whether the service counts as up, end-to-end latency in milliseconds, response size, server and content-type headers. For HTTPS endpoints it opens a TLS connection with certificate capture and reports the issuer, subject, SANs, expiry timestamp and days remaining — catching expiring certificates two weeks out. A security-header audit checks HSTS, Content-Security-Policy, X-Content-Type-Options and X-Frame-Options. Problems come back as named issues: UNREACHABLE, SERVER_ERROR_STATUS, SLOW_RESPONSE (>3s), CERTIFICATE_EXPIRING (<14 days), CERTIFICATE_EXPIRED. At $0.005 per probe, an agent checking a service every 5 minutes spends about $1.44/day for full uptime + certificate monitoring with no subscription. All probing is SSRF-guarded and server-side.",
