Pulling resource planner allocations via API

Hello, is it possible to retrieve resource allocations from resource planners via API? I’m using a stand-alone capacity manager to summarize resource allocation but it has a limit of 50 connected planners. As a result, it seems like pulling the data via API and writing custom reporting is my only alternative. I don’t see anything that specifically mentions resource planner data in the API reference, assuming these data points are treated as items under boards? Going to keep testing but wanted to reach out in parallel. Appreciate any insights.
