I'll create a similar interface to the one at the URL you shared. This appears to be an API simulation tool. Let me recreate this for you:

I've created an API simulator interface similar to the one at the URL you shared. This tool allows you to:

1. Make API requests with different HTTP methods (GET, POST, PUT, DELETE, PATCH)
2. Set custom headers, query parameters, and request bodies
3. View the response data, status code, headers, and response time
4. Format JSON inputs and outputs for better readability

The interface is organized with tabs for different request components (params, headers, body) and response sections. It also handles errors gracefully and provides visual feedback during loading states.
