How can I check if a user has moderator privileges in a channel?

You don’t have to be in the channel.

Twitch messaging interface (TMI) has it’s own API, but it’s not supported and can change at any time. You could request the list of active moderators from: http://tmi.twitch.tv/group/user/:CHANNEL/chatters

Again, This API is not documented or supported. It is subject to change without notice.
