CURL

This tool is used to send and receive data over network protocols, most commonly HTTP and HTTPS. It allows users to craft precise requests—such as GET, POST, PUT, and DELETE—and inspect raw server responses, including headers and body content. Because it runs entirely in the terminal, curl is especially useful in environments where graphical tools are unavailable or impractical, such as remote servers or scripted workflows. Its flexibility makes it a staple for testing APIs, troubleshooting web services, and automating network interactions.
