How to Design a Rate Limiter API | Learn System Design

Rate limiting controls the rate of incoming requests to prevent server overload and ensure fair usage.

The rate limiter API should support multiple rate-limiting rules, error handling, and scalability. It is typically implemented server-side for better security and flexibility.
