Who has access to the various dental X-ray SDKs?

Question

C++ / C#

Good day.
I am developing a universal access library for obtaining images from dental x-ray machines in C#. Twain and DIDAPI SDK are already implemented. Interested in the latest SDK versions for Schick, Sirona, DentalMind, CareStream, Instrumentarium Snapshot. They are not publicly available. You need to be a representative of a dental clinic or buy the device directly.
Maybe someone has the opportunity to share such SDKs.
