What is API rate limiting and why is it important?

API rate limiting is a technique used to control the amount of incoming requests to an API. It's important to prevent abuse, ensure fair usage, and maintain performance.

How does rate limiting work in practice?

In practice, rate limiting can be implemented using various algorithms like token bucket or leaky bucket, which define how many requests a user can make in a given time frame.

What happens if I exceed the rate limit?

If you exceed the rate limit, the API will typically return an error response, often with a status code like 429, indicating that you've made too many requests.

Can I request a higher rate limit?

Yes, many APIs allow you to request a higher rate limit, usually by upgrading your plan or contacting support.

Are there best practices for managing API rate limits?

Yes, best practices include implementing exponential backoff for retries, monitoring usage, and caching responses to reduce unnecessary requests.
