The question was asked before in a different form, but was not actually answered (https://forums.ashesofcreation.com/discussion/45678/developer-apis).

I think it would be a good idea to have API's for guild maintenance outside the game itself, or at least an API for retrieving the guild roster outside the game to help guild to organise themselves not only inside the game.
