These are the URLs that you will point your development environment to. Most development environments provide a way for you to specify the URL of a web service and will then auto-generate some web service connection classes for you. What this essentially does is make the web service nothing more than a function call in your application.
Here are the end points for the CalcXML web services. You will notice that they are organized by category, so each end point, or wsdl file, contains multiple calculators. You can ignore any that you do not want or that you do not have access rights for.
