I couldn’t find a set-and-forget monitoring API, so I built one with automated webhook alerts

### Production-Grade SSL, Domain Expiry & DNS Monitoring This API provides an automated, headless monitoring system that continuously tracks your public assets and alerts you via webhook before infrastructure issues affect your users. #### Key Features: * **Full Chain-of-Trust Validation:** We inspect the entire certificate chain (root and intermediate certificates) to detect hidden expiration issues. * **Certificate Change & Substitution Detection:** Track SSL fingerprint and serial number shifts to catch unauthorized renewals, man-in-the-middle substitutions, or silent config changes instantly. * **Domain Expiry Safeguard (WHOIS/RDAP):** Monitor registry records to prevent domains from expiring or being sniped by third parties. * **Rogue Certificate Alerts (CT Logs):** Track public Certificate Transparency (CT) logs to find unexpected certificates issued for your registered domains. * **DNS & Hijacking Protection:** Snapshot your DNS records (A, MX, TXT, NS) and get notified if any records are altered or hijacked. * **Zero-Configuration Webhooks:** Integrate with Slack, Discord, or raw JSON payloads to deliver styled markdown alert cards to your communication channels instantly.
