What is cURL?

cURL (Client URL)  is a command-line tool that is used by developers to download data from a server or upload data to a server.

The curl lets us interact with a server by specifying an address (URL) and the data we want to send or receive.

Example

Let’s see what we get when we use curl on http://www.example.com/.

We’ll see that it has returned the code of the webpage (http://www.example.com/) in return for our request.
