get the name of the rigid bodies and markers

[nag92]

is it possible to get the name of the markers and rigid bodies using the SDK?

TL;DR - Yes.

It is possible to get both the name of Rigid Bodies as well as the name of labeled trajectories using the RT Protocol (see QTM RT protocol). Although the syntax of course differs depending on which SDK you're using.

I took a quick look at THIS example code in the Python SDK, and found the following:
# Get 6dof settings from qtm
xml_string = await connection.get_parameters(parameters=["6d"])
body_index = create_body_index(xml_string)

It's in create_body_index that the XML data retrieved from the RT Protocol is parsed. In this particular example, you might change "6d" --> "3d" in order to obtain the marker data you're seeking.
