guild/:id does not match its example
API is down for the moment (Lawton disabeld it until tomorrow evening), so i can’t check. But i can tell you that: wiki is maintained by players, like you and me, and if this endpoint changed and nobody reports the changes on the wiki…

Some fields are only returned when you request the guild endpoint with an api key of the guild leader, otherwise you will only get public data.
