APIs sit at the center of modern digital systems. They power mobile apps, enable partner integrations, and connect internal services across distributed architectures. When an API fails, the impact is immediate: broken user journeys, stalled transactions, and downstream systems that quietly stop working. That’s why API health monitoring is now a core reliability practice for modern engineering teams. The problem is that “API health” is often defined too narrowly.
