The simple answer is that there is no API involved. It can all be done using generic VFP commands and techniques.

You need to start with an application timer. This will create the running clock when users are not doing anything.

Next you need to keep track of when a user does do something. Windows can do this fairly easily because it is "aware" of everything you do within its environment. The simplest approach is to modify your baseclasses (textboxes, spinners, etc) so that changes to them register to the application as "activity". You can put code in the InterActiveChange to do this.

To register activity, create a custom property of an application object (or create a global variable) that holds the datetime of the last user activity. When the application timer fires, check the last datetime of user activity and if it beyond a certain threshold, exit your application.

This should get you started. There are more involved approaches and you can make it as complex as you want.

HTH.
