Pulse API
Sentiment analysis infrastructure for the social web.
In DevelopmentWhat is Pulse API?
Pulse API gives you direct access to the infrastructure powering Chorus. Query Reddit and YouTube for posts and comments, then analyze them with our sentiment and emotion detection systems.
It's built for consultants, researchers, and businesses who need to understand public sentiment at scale — without building and maintaining their own scraping and analysis infrastructure.
