I have an activity diagram with initial and Final Nodes in it. Both are of type StateNode and the meta type is Pseudostate. How to identify whether a particular node is an initial or final node from the Database or API point of view?

You can use EA.Element.Subtype
From the documentation
Long
Notes: Read/Write
A numeric subtype that qualifies the Type of the main element
- For Event: 0 = Receiver, 1 = Sender
- For Class: 1 = Parameterised, 2 = Instantiated, 3 = Both, 0 = Neither, 17 = Association Class
If 17, because an Association Class has been created through the user interface, MiscData(3) contains the ID of the related Association; as MiscData is read-only, you cannot create an Association Class through the Automation Interface.
- For Note: 1 = Note linked to connector, 2 = Constraint linked to connector
- For StateNode: 100 = ActivityIntitial, 101 = ActivityFinal
- For Activity: 0 = Activity, 8 = composite Activity (also set to 8 for other composite elements such as Use Cases) For Synchronization: 0 = Horizontal, 1 = Vertical
Note that there are many more Types than indicated in these examples.
