Throughput, or request rate, measures how many requests an API processes within a time window. In the RED method, it is one of three service metrics, alongside error rate and duration. section 11.2.1 section 11.2
Tracking request rate across different periods helps reveal API usage trends and patterns. API teams use it as part of technical performance monitoring; product metrics also inform decisions and improvement goals. section 11.2.1 section 11.4
