language, tweets to/about/from specific users, more.• Retrieve trends, find out what´s hot on twitter

programmatically.

REST API v.1.1

• 87 methods mirroring nearly all of twitter's user-facing features• Returns XML or JSON for all methods, RSS and ATOM for

methods that return timelines.• Supports JSON callbacks, a variety of parameters to

slice 'n dice.• Meaningful use of HTTP response codes, plus

explanatory error messages in the requested format.
