Uptime Monitoring API

A developer-first uptime monitoring API with clean JSON and predictable checks. Pull uptime history, response time trends, and SSL metadata into the tools you already use.

Built for automation, reporting, and AI workflows.
Example JSON response from the Site Informant uptime monitoring API.

Who this is for

  • Developers who want programmatic uptime data
  • DevOps teams who prefer signal over noise
  • Agencies building reporting into client workflows
  • Teams building AI tools that need reliable status context

What you get in the API

Uptime history
Pull availability results and understand reliability over time.
Response time trends
Detect slowdowns and drift before it becomes downtime.
SSL and TLS metadata
Issuer, expiration, and protocol information for operational visibility.
Authenticated endpoint monitoring
Attach allowed request headers to monitor protected routes. Values are stored encrypted and never shown publicly.

AI-ready monitoring

When you have an incident, your tools need context. The API makes monitoring data easy to pull into automation and AI workflows so you can answer practical questions quickly.

Example
“Is this endpoint actually down, or just slow from a routing change?” Use response time and IP resolution history to confirm.
Example
“Which client sites had elevated latency in the last 24 hours?” Pull trend data and generate a report automatically.
