I agree that there needs to be a way to discover API endpoints. Especially with the [brave new world of SE 2.0][1] potentially leading to an ever increasing number of API-ified sites out there. However, there isn't a good place to shove this functionality just yet. Currently, we only have two places it *could* go: - api.[stackoverflow|superuser|serverfault|meta.stackoverflow].com - not "global," and accordingly shouldn't know about all the other sites in the network - api.stackapps.com - more "global," than the above, but also a site onto itself; it'd be a weird one-off to also have it serve up a network map A similar problem exists with getting user associated accounts. In short, once there is a place for this data to come from it'll be made available. Most likely, this will exist "out of band" from the regular API.
