Uptime Monitoring API

A developer-first uptime monitoring API with clean JSON and predictable checks. Pull current uptime, average response time, and SSL metadata for opted-in public endpoints into the tools you already use.

Built for automation and reporting.
Example JSON response from the SiteInformant 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 internal tools that need reliable status context

What you get in the API

Uptime history
Read the current retained uptime percentage for an opted-in endpoint.
Average response time
Read the current average response time included in the public status response.
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.

Automation-ready monitoring

When you have an incident, your tools need context. The API makes monitoring data easy to pull into automation and reporting systems 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
“What uptime and average response time is this client endpoint reporting now?” Read the opted-in public status response and add it to your report.

Private dashboard capabilities are separate

Retained p95 response time, deployment impact comparisons, private endpoint history, notification destinations, and escalation policies are authenticated account features. They are not exposed through the anonymous public status API.

See p95 and deployment performance tracking.
