There are many wonderful community tools that have popped up over the course of WoW’s history, that rely upon the API for profiles added in later expansions, such as quest or mount tracking, or character gear recommendations. Will there be classic support in the API?
I think we plan to do it, but not sure if we'll have it for launch. We're trying to make sure that API is available, but the timeline for launch we're unsure about.

Q. Will there be an Armory for WoW Classic?
A. There was no Armory for World of Warcraft until the Burning Crusade. If you wanted to know more about a player’s gear before you invited them to your party, you had to meet them in the world and physically inspect them (and you couldn’t inspect players of the opposite faction until 2.4). You couldn’t see their spec or talent builds when you inspected them, either. To maintain that same dynamic, we won’t have an Armory or profile pages for WoW Classic at launch.
