Question 1

What is cURL?

Accepted Answer

cURL is a command-line tool and library for transferring data with URLs. It's available on most operating systems and is widely used by developers to test APIs, download files, and send HTTP requests from scripts.

Question 2

How do I send a POST request with JSON using cURL?

Accepted Answer

Select POST method, paste your URL, add a Content-Type: application/json header, paste your JSON body in the Body field, and the tool generates the complete cURL command with -X POST -H and -d flags.

Question 3

Can I add Basic or Bearer authentication?

Accepted Answer

Yes. Add an Authorization header in the Headers section. For Basic auth use the value 'Basic ' followed by base64-encoded username:password. For Bearer tokens use 'Bearer YOUR_TOKEN'.

Question 4

Does this tool actually send the request?

Accepted Answer

No. This tool only generates the cURL command for you to copy and run in your own terminal. It does not send any requests from your browser, so CORS and authentication issues are not a concern.
