 ### `get_network_request`
 
-**Description:** Gets a network request by URL. You can get all requests by calling [`list_network_requests`](#list_network_requests).
+**Description:** Gets a network request by reqid. You can get all requests by calling [`list_network_requests`](#list_network_requests).
+Get the request currently selected in the DevTools UI by ommitting reqid
 
 **Parameters:**
 
-- **reqid** (number) **(required)**: The reqid of a request on the page from the listed network requests
+- **reqid** (number) _(optional)_: The reqid of the network request. If omitted, looks up the current request selected in DevTools UI.
