API Rate Limiting & Scalability Patterns · Lesson

Basic Rate Limit Concepts

Learn fundamental terms like request quotas, time windows, and the impact of exceeding defined limits on API consumers.

Welcome to Rate Limit Basics

A request quota is the max number of requests an API lets you make — the how many of a rate limit, protecting the API from overload.
