No

Because nikic fastroute doesn't support it. You have to specify each route.

How to group routes in Laravel Lumen framework.

.......... $app->group(array('prefix' => '/api'), function() use ($app)
.......... {
	// Version group
.......... .......... $app->group(array('prefix' => '/v1'), function() use ($app){
.......... ..........$app->get('users/', function() use ($app) {
.......... ..........return 'hello';
.......... .......... });
.......... });

});

When searched {URL}/api/v1/users it returs page not found error, but works when searched for {URL}/users

Yeah, as CedNet said, FastRoute doesn't support this.
