Google has announced its latest API with a haiku of all things:
New admin tool dawns
Settings change like the seasons
For hosted email
That's from Andrew Olsen of the Google Apps team, announcing the Google Email Settings API, which allows IT administrators at organizations that use the Gmail-based Google Apps hosted webmail solution to "programmatically update Gmail settings for their users in bulk by making requests to a GData feed." Previously, settings could only be changed manually, on an account-by-account basis.
An email address can be the key to an online identity, and that's just what IDLight is using in its identity lookup API. By supplying either an email address or a URL to the IDLight API you could be turning the key to unlock a swath of identity information.
