Care to expand on that? The API is not i18ned (apart from the content, obviously), the only thing vaguely similar to what you wrote which I can see are the names of the special pages. But even though they are translated into the wiki content language, on input, every wiki accepts the English version as well. Also, the canonical identifier is present in the page for scripts to use. Or, what problems do you have?
