API wrapper

An API wrapper is a code abstraction layer: it converts complex, low-level HTTP requests and JSON parsing into simple, high-level, language-specific function calls for streamlined development.

An API wrapper is a critical intermediary layer that simplifies interaction with a raw API. It handles repetitive, error-prone tasks: specifically, managing HTTP headers, token authentication, and parsing the full JSON response payload. For example, instead of writing 15 lines of code to fetch a user profile, you call one clean method, like `get_user_profile()`, which returns only the necessary data object. This abstraction significantly reduces boilerplate code, improves maintainability, and ensures your application logic remains decoupled from the underlying API's specific mechanics.
