I have been using Multilingual App toolkit to translate resx files but recently it stopped working with the error message below. I thought that it is free and unlimited. Did I reach some certain limit? When I say Yes, nothing happens, no translation at all.
One other question, is it even possible to add a new provider like google translate? I thought that i watched on some presentation was saying it is possible but I couldn't figure it out how.

They moved to Azure Portal and it is paid service looks like now.

EDIT: Obviously single word translation is still supported for free but more than single word for a key doesnt work any longer.
