problem with Routing HTTP API Examples

i have followed this example to try to trace the itinerary between two points :

http://developers.cloudmade.com/projects/routing-http-api/examples

However in the example there is no notification of where to put the http query : http://routes.cloudmade.com/YOUR-API-KEY-GOES-HERE/api/0.3/start_point,[[tr开发者_运维问答ansit_point1,…,transit_pointN]],end_point/route_type[/route_type_modifier].output_format[?lang=(en|de)][&units=(km|miles)] Any help will be appreciated.

there are query examples like
