Layer7 API Management

We'd like to embed the CA API SaaS Portal  in our home grown portal application & would like to understand the below possibilities:

1. Are there any APIs available for the SaaS portal that can be utilized to leverage the data managed by the portal. Please note that we are specifically looking at portal APIs and not gateway mangement APIs as listed here: https://docops.ca.com/ca-api-gateway/9-1/en/apis-toolkits-and-sdks/rest-management-api
2. Feasibility of other options - SSO, UI embedding, portlet integration, etc.
3. Any suggestions on additional approaches for the use case?

PAPI seems to be the way to approach this use case

Is there any documentation available for the PAPI?
