API monitoring is the continuous process of tracking the availability, performance, and correctness of APIs in real time. As APIs form the backbone of modern applications, even minor degradations—such as increased latency or unexpected response changes—can directly impact user experience and downstream services.
Unlike pre-release testing, API monitoring focuses on observing behavior in live environments. It helps teams detect issues like uptime failures, slow responses, schema mismatches, and error-rate spikes before they escalate into major incidents. This visibility is especially critical in microservices and distributed systems, where a single failing API can cascade across multiple services.
Effective api monitoring combines health checks, performance metrics, and alerting with contextual insights from logs and traces. When aligned with CI/CD pipelines and automated testing, monitoring closes the feedback loop between development and operations, enabling faster root-cause analysis and more resilient systems.
API monitoring is not just an ops concern—it’s a shared responsibility that strengthens reliability across the entire delivery lifecycle.
