The new version of the service allows data consumers (services like Plaxo that take data from other services, like Twitter, Friendfeed, Digg, Delicious, etc.) to have data from requested users pushed to them. It’s no longer “Hey, TechCrunch just tweeted. Go query the API to get the data.” Now it’s “TechCrunch just tweeted – here’s the data.” Data consumers are no longer required to build pollers for any of the publishers pushing data into Gnip, they just give Gnip an endpoint and they push the data to them in real time.
Data consumers can get complete public data streams for Twitter, Digg, Delicious, Six Apart and others without ever visiting those sites or accessing their individual APIs, subject only to the terms of service of those services. And this data can be gathered via a REST-based API or the newly launched XMPP support.
Gnip also added a number of filter options to allow data consumers the ability to create rules based queries based on tags, keywords, etc.
Gnip’s business model is freemium – lots of data for free and commercial data consumers pay when they go over certain thresholds (non commercial use is free). The model is based on the number of users and the number of filters tracked. Basically, any time a service is tracking more than 10,000 people and/or rules for a certain data provider, they’ll start paying at a rate of $0.01 per user or rule per month, with a maximum payment of $1,000 per month for each data provider tracked. For now billing is turned off and the service remains completely free. Thirty to sixty days from now, people will start to pay.
