Answer
A health-check endpoint responds with a status like OK to help monitoring tools verify app uptime.
Quick Answer
A health-check endpoint (usually GET /health or /ping) returns a quick status indicating whether the app is running correctly. Load balancers, Kubernetes readiness probes, and monitoring tools ping it periodically. It should check DB connectivity, cache availability, and critical dependencies — returning 200 if healthy, 500+ if not.
