What is Curl?
A versatile command-line tool for transferring data using various network protocols, commonly used for API testing.
Curl supports HTTP, HTTPS, FTP, SFTP, and many other protocols. It is the go-to tool for API testing: curl -X POST -H "Content-Type: application/json" -d '{"key":"value"}' https://api.example.com/endpoint.
Useful flags: -v (verbose), -o file (output to file), -L (follow redirects), -k (ignore SSL), -u user:pass (authentication), -b cookie (send cookies). Curl is installed on virtually every Linux system.
