Open API for get MBPLE transformed model

Hello All,

I am looking for Open API to get transformed model/project with selected instance of feature model (configured model) .

My expectation is as below:

I have created project in Cameo and configured using PLE plugin. Then I have transformed that model with one of the instance/feature model and save it.

Now I want information that with available OpenAPI:

Which API can give me information about all elements and relations ?

Which API can we use to query transformed model and non-transformed (150%) model?

Do we need to use openAPI to transform model as per selected variant using API and then can get information of transformed or configured model of all elements and relations and properties ?

Thanks for your support and help on this topic.
