Sentiment Analysis API

Perform deep sentiment analysis on any text using Claude-powered AI. Unlike simple positive/negative classifiers, this API provides aspect-level sentiment — detecting which specific topics or features are positive or negative in a review or feedback item.

How it works

POST your text. The API returns an overall sentiment (positive/negative/neutral/mixed) with a confidence score, a list of detected sentiment aspects with their individual scores, and key phrases that drove the sentiment classification.

Use cases

• Analyze product reviews to find which features customers love or hate
• Monitor social media mentions for brand sentiment tracking
• Triage customer support tickets by emotional urgency
• Analyze employee survey responses for HR insights
• Build real-time sentiment dashboards for customer feedback streams
