What are API Clients for Visual Studio Code?

API clients are software tools or libraries that enable applications to communicate with APIs (Application Programming Interfaces) by sending requests and handling responses. They simplify the process of making authenticated calls, formatting requests, and parsing data returned from remote services. API clients often include features for error handling, retries, and rate-limiting to ensure reliable integrations. Many are available in multiple programming languages, making it easier for developers to interact with web services and backend systems. By abstracting the complexity of direct network communication, API clients accelerate development and help maintain clean, maintainable code.
