An HTTP monitor periodically requests a public health endpoint. Still200 records availability and response time, classifies dependency health, and opens an incident after repeated failures.

​
Simple response

The smallest valid endpoint returns a service name with HTTP 200:

​
Dependency-aware response

Add a checks object to report latency or an error for each dependency:
Still200 derives each check’s status. An error is unhealthy, latency above 1,000 ms is degraded, and other results are healthy.

Health-check specification

Review every request and response requirement.

Implementation examples

Build a dependency-aware endpoint.
