I am looking for a service where I can query or request Twitter tweets based on a specific #hashtag or keyword. Is this something your service can do for us?
DiscoverText.com can do that and gather tweets “day forward,” meaning from the time you submit the query until you stop it. It is free for 3 days.
See the 3-day free trial article for more information.
Sifter.texifter.com can do that for historical tweets.
Unfortunately, the Sifter service and website has been decommissioned as of September 30, 2018. Thanks to our 6,970 users who created 16,128 free estimates from the complete, undeleted history of Twitter between 1/14/2014 and 9/29/2018.
Please contact Twitter for approval of future academic or commercial use cases. If you can get an approved use case and a contract from Twitter, we can still help you work with the data inside DiscoverText.
@DiscoverText remains open and is still the top-ranked text analysis platform on the Internet.
All paid jobs prior to the decommissioning will still be honored.
