I actually posted a question in the "Ask us anything" thread about giving us access to an API so that we can develop our own apps and informational websites.
The ESO community has a lot of bright, savvy people, so I'd be really interested to see what kind of creations they'd come up with.
The API could give us access to research times, bit an ally, and even things like the status in Cyrodiil. Get an alert on your phone that a home keep is under attack, tell your boss you have severe diarrhoea and need to rush home just in time to save the day. Thanks ESO API!
