How this service works
Sentiment Analysis: sentiment, polarity score and emotions for any text Executed deterministically by the AmanChain node against live consensus state (real blocks, pools, balances) — paid per call via x402, settled in USDC on Base. Input: JSON body {"serviceId":"aman-sentiment","request":"<input>"}. No account, no API key.
Output
Returns a sentiment classification (positive, negative, or neutral), a numeric polarity score indicating strength and direction of sentiment, and a set of detected emotion labels (e.g. joy, anger, sadness, frustration) for the submitted text.
Example use cases
Customer review sentiment scoring
“Analyze the sentiment and emotions in this product review: 'Absolutely love this! Fast shipping, great quality, exactly what I expected — will definitely buy again.' Tell me if it's positive, negative, or neutral and give me the polarity score.”
Social media brand monitoring
“I need to know the sentiment and emotional tone of this tweet about our brand: 'Can't believe how long I've been waiting on hold with support. Totally unacceptable for a premium service.' Is it negative? How negative, and what emotions are present?”
Support ticket triage by emotion
“Check the sentiment and detect any emotions in this support ticket message: 'I've tried everything and nothing works, I'm completely lost and really frustrated. Please help me urgently.' I want to know the polarity score so I can prioritize it.”
