Daily Term: API Rate Limiting

API Rate Limiting

API Rate Limiting controls the number of requests a client can make to an API within a specific time period to prevent abuse or overload. For example, an API might limit users to 500 requests per hour, rejecting additional requests until the limit resets. Techniques include fixed windows, sliding windows, or token buckets. Rate limiting ensures fair usage and protects server resources but requires careful tuning to balance usability and protection.
