About Certificate expiry alerts
Keep an eye on expiring SSL certificates. Create and manage workspace HTTP, certificate, DNS and heartbeat monitors with owner email or webhook alerts.
When to use it
Track your own endpoint, certificate, DNS records or scheduled job and inspect actual check results.
POST /api/monitors
{ "kind": "http", "name": "My API", "target": "https://api.example.com/health", "intervalSeconds": 300 }
GET /api/monitors/{id} → status, lastDurationMs and recentChecksHow to use it
- Sign in and create a monitor for your public endpoint or domain.
- Choose a check interval and optional alert webhook; verify the owner email for email alerts.
- Review current status and recent check times. For DNS, review changed records before accepting a new baseline.
Limits & privacy
Free permits twenty monitors at intervals of five minutes or slower; Pro one hundred and Team five hundred, every minute or slower. Active failures are confirmed before alerting. The latest fifty check timings and fifty status changes are retained. DNS uses a public resolver and ignores TTL changes; it does not identify the domain hosting provider. Changes remain flagged until the workspace accepts new records. Targets and alert destinations are private to the workspace.
Use this tool from the API reference or connect through the SDK, CLI, SSH, or MCP. Hosted calls share your plan allowances.
