Twitter today announced two new application programming interfaces that developers can use to integrate data from the Twitter’s Gnip service into third-party apps.

They’re not just meant to provide tweets, which Gnip already does. Rather, these new ones — the Audience API and the Engagement API — will provide information about reach for and impressions on tweets. Until now Gnip has only had the Realtime and Historical APIs.

Both of the new APIs are in beta, Chris Moody, Twitter’s vice president of data strategy, said today at its Flight developer conference in San Francisco.

“The Engagement API is going to let you as developers help your customers understand what’s happening with their organic content, so you can help them understand things like impressions, which have never been programmatically available — no more guessing about impressions,” Moody said.

The Audience API provides granular information about brands’ audiences.

“We’re surfacing … demographic and psychographic analysis that we’ve never surfaced before,” Moody said.

Twitter bought Gnip last year.

Startups participating in the Techstars accelerator will have free access to Gnip’s data sources, said Moody, who noted that Gnip has gotten feedback that its services are expensive. But beyond that, this is an olive branch to third-party developers, reflecting newly reinstated Twitter chief executive Jack Dorsey’s desire to “reset” relations with developers.
