Open Access Flag for Open Access Content
Open Access Content in Primo Central should be marked with an open access flag in the search or the facet section.
As a result it should be possible to search or filter on open access content regardless of the frontend (Primo or via API).
Thank you for your contribution
Open Access indicator & filter has been added to Summon, following analysis of the feedback for this enhancement in Summon we will evaluate the addition of Open Access indicator & filter to Primo Central.

There is also already something planned for Primo in 2017:
Enhanced Metadata Quality: Increase population of Open Access indicators and ORCiD
