How does rate limiting work?

Can you explain how rate limiting works in APIs?

Rate limiting is a technique used to control the amount of incoming requests to a server. It helps prevent abuse and ensures fair usage.

Why is rate limiting important for APIs?

It's important because it protects the server from being overwhelmed by too many requests, which can lead to downtime or degraded performance.

What are some common methods of implementing rate limiting?

Common methods include token bucket, leaky bucket, and fixed window algorithms. Each has its own advantages and use cases.

Can you give an example of a rate limiting policy?

Sure! A common policy might allow 100 requests per hour per user. If a user exceeds this limit, they receive a 429 Too Many Requests response.
