FAQ

What is an API request builder?

It's a visual tool for constructing HTTP requests without writing code. You fill in the method (GET, POST, etc.), URL, headers, and body — the tool assembles and sends the request, then displays the response.

Can I test REST APIs with this tool?

Yes — enter your API endpoint, add Authorization headers or API keys, set a JSON body for POST requests, and send. The response body, status code, and headers are displayed immediately.

How is this different from Postman?

Postman is a full desktop app with workspaces, history, and team features. This tool runs entirely in your browser with no installation, no account, and no data stored — perfect for quick one-off requests.
