Pulse API

Sentiment analysis infrastructure for the social web.

In Development

What 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.

What You Get

Reddit Access

Search posts, pull comments, access any subreddit. No rate limit headaches.

YouTube Access

Pull video data, comments, and engagement metrics at scale.

Sentiment Analysis

Positive, negative, neutral — for every post and comment.

Emotion Detection

Joy, anger, fear, surprise, sadness, disgust — nuanced emotional understanding.

Trend Analysis

Track how sentiment changes over time for any topic.

Aggregation
