What is an API wrapper and why would you use one?

An API wrapper is a set of programming instructions that act as an intermediary between an application and an API, simplifying the process of interacting with complex APIs by providing a more user-friendly interface. This intermediary layer abstracts the complexity of direct API calls, such as handling request URLs, query parameters, and HTTP headers, allowing developers to use simpler commands and focus on creating functionalities rather than managing intricate API details. API wrappers are often tailored to specific programming languages, offering idiomatic usage and built-in error handling, which enhances the developer experience by providing clear feedback and facilitating efficient application development. They can also be customized to fit specific project needs, streamlining the development process and boosting code effectiveness. Examples like the Python wrapper PyGallica demonstrate how wrappers can simplify access to complex data sources, making the development process smoother and more intuitive.
