The business of monitoring, measuring and understanding social media
Twitter introduced a new set of "premium APIs" to fill a perceived gap between the company's standard APIs and its enterprise-level Gnip services. The first premium API is the Search Tweets API, which provides 30 days of historical data and starts at $149/month. A full historical search API is planned to be next.
