The URL of a REST API for zCEE is a combination of the basepath that is set when you create an API Project in the zCEE API Toolkit plus whatever is set in each API you create in the API project.
The basepath must be unique within a zCEE server
If you wanted
www.mainframe.com/billing , then you would create an API project with the basepath set to billing, and for
www.mainframe.com/requests , you would create another project with the basepath set to requests
In example below, the URL for the API would be hostname/zofficev1api/catalog/<number>

There is no web server as such with zCEE, as it is a Liberty server that is receiving the REST APIs requests
