I’m investigating Wiki API and I do not see how to determine language of the Page. There is prop=langlinks for action=query but it does not work. For example this command for Alminav does not return entries for English and German.
And it is not exactly what I need.
Another question is it possible to return timestamp of last modification of the page in the “list=embeddedin” request? Looks like standard Wiki API does not support it. Can you extend this API?
