Our problem is how to save a UI code in WikiSource server? The engine runs well on a rented server and I guess the principle workflow is the same only running on different server. The problem is that we do not know the address of WikiSource server, or an access to put (write/save) our UI (API) code to that server. It seems trivial but it turns out complicated if we have no access.

Does the service has an API that can be used to fetch the OCR text?

We are developing the API for it, but have no idea on how to connect to the Wiki server.
Is there any guidance for sending and requesting data to and from Wiki server? Do we need to have specific account?
I would be very grateful for your information on having connection to Wikiserver.
