Description: API caching is the process of storing API responses to improve performance and reduce load on servers. This mechanism allows applications to access previously requested data without needing to make a new API call, resulting in faster response times and lower resource utilization. Caching can be implemented at different levels, whether on the client side, server side, or in intermediaries like proxies. Cached responses can include static or dynamic data, and their validity can be controlled through expiration policies that determine when the information should be updated. The implementation of API caching is particularly relevant in environments where latency and efficiency are critical, such as web services and microservices. By reducing the number of requests to servers, caching not only enhances user experience but also optimizes bandwidth and computational resource usage, contributing to a more scalable and efficient architecture.
