Google API Explorer

First of all the UI for this page is neat, that I can select the service first, then the Version, and then the API/Method.

This page contains the list of Google APIs exposed along with the versions. The more cool part is to execute them and see the responses in the same page!

I suppose the list of Service will expand to many Google products.

It would be excellent to have the code.google.com APIs as well listed as here...
