cURL tutorial boils servers down to broke friends begging for cash: because APIs are just awkward IOUs in command-line disguise

In the world of computer networking, servers play a crucial role in processing requests and providing responses. A server is essentially a hardware or software system that handles requests sent over a network, returning data, sending data, updating data, or removing data as needed. To interact with these servers, developers use a command-line tool called cURL, short for "Client URL". cURL enables users to transfer and download data to a specific server by specifying the location in the form of a URL. Programmers widely use cURL to perform quick HTTP requests, including GET, POST, and other types, making it an essential tool for testing APIs, particularly among backend developers. By using cURL, developers can fetch websites, send requests, and retrieve data from servers, with examples including fetching a website's HTML or sending GET requests to retrieve data from a server, such as retrieving a list of products from a dummy JSON server.
