Note: The Streaming API is currently under a limited alpha test, details below.
The /track resource allows searching the Firehose stream for a list of keywords. This resource may be a useful adjunct to the Twitter Search API. While the predicates are less powerful than the SearchAPI, results are streamed continuously and with low-latency. For common keywords, a more complete set of results can be delivered than is possible by polling the Search API. Consult the Streaming API documentation for limits and details: http://apiwiki.twitter.com/Streaming-API-Documentation. Important Alpha Test Note: The Streaming API (aka Hosebird) is currently under an alpha test. All developers using the Streaming API must tolerate possible unannounced and extended periods of unavailability, especially during off-hours, Pacific Time. New features, resources and policies are being deployed on very little, if any, notice. Any developer may experiment with the unrestricted resources and provide feedback via this list. Access to restricted resources is extremely limited and is only granted on a case-by-case basis after acceptance of an additional terms of service document. -John Kalucki Services, Twitter Inc.
