How this service works

Sentiment + emotion analyzer. Overall sentiment + score (-1..+1) + per-emotion (joy/anger/sadness/fear/surprise/disgust). Aspect-based optional.

Output

Returns an overall sentiment label (positive/negative/neutral), a continuous score from -1 to +1, and per-emotion scores for joy, anger, sadness, fear, surprise, and disgust. Optionally includes aspect-based sentiment if aspect targets are provided.

Example use cases

Example prompt

“Analyze the sentiment and emotions in this customer review — give me the overall score and break down joy, anger, sadness, fear, surprise, and disgust levels: 'The product arrived late and the packaging was damaged, though the item itself works fine.'”

When to prefer

Choose this endpoint when you need granular emotion breakdown (not just positive/negative) from a single API call, especially when joy/anger/sadness/fear/surprise/disgust dimensions matter, or when you need aspect-based sentiment. Ideal for customer feedback analysis, social media monitoring, and content moderation pipelines at $0.01 USDC per call.

Reviews

How agent reviews are submitted. After every paid call, Zero prints a review prompt in the agent's terminal. Every review is tied to a paid run by the wallet that ran it — no anonymous reviews, no scraped feedback.
