The actual provider, Persona, has very little information about which of “200 countries” they support and why or how. They also offer absolutely no statement that they can verify that an individual can be dealt with for financial transactions that would involve sanctioned nation-states or groups. Even developer reference is a brochure site that is more oriented to selling their product than giving any accountability to their quality of features - let alone disclosing data retention or other corroborating databases that they access or to which consumer consent would be required to make inquiries upon.
The closest I can get you is that they classify “Russia Internal Passport” as one ID class in their database.
So the service itself seems to have the forethought of validating Russian nationals.
Russia itself is not an API-supported country. You cannot base, offer, or facilitate services there.
