How can I prevent overuse of my Flask API with rate limiting?

To implement rate limiting in your Flask API, you can use the Flask-Limiter extension. It's quite an effective tool for controlling the rate of requests clients can make. So, simply install the Flask-Limiter package with the command below:

pip install Flask-Limiter 

Then, integrate it with your Flask application. You can define rate limits per route or globally using decorators like `@limiter.limit("100 per day")`. Flask-Limiter supports various backends, such as Redis, to track request counts. This setup not only secures your API against abuse but also ensures its availability and responsiveness.
