How this service works
Sentiment analysis API — text sentiment score with polarity, emotions and positive, negative or neutral classification; social media and review sentiment, real-time. Deterministic on-chain execution by the AmanChain node — live consensus state, real blocks, pools and balances. Pay per call via x402 (USDC on Base), no account, no API key. POST JSON {"serviceId":"aman-sentiment","request":"<input>"}.
Output
Returns a sentiment label (e.g. positive, negative, neutral), a numeric polarity score indicating strength and direction of sentiment, and a breakdown of detected emotions (e.g. joy, anger, sadness, fear, surprise) present in the input text.
Example use cases
Customer review tone classification
“I have this customer review and I need to know if it's positive, negative, or neutral, plus what emotions come through — can you run sentiment analysis on it: 'Absolutely love this app, it's made my mornings so much easier even though the learning curve was steep at first.'”
Social media brand monitoring
“Analyze the sentiment and emotions in this tweet about our brand: 'Can't believe @AcmeCorp still hasn't fixed the login bug after 3 weeks. Frustrated and losing trust fast.' — I need the polarity score too.”
Support ticket emotional triage
“Run sentiment and emotion detection on this support ticket so I can prioritize it: 'I've been waiting two weeks for a refund and no one is responding to my emails. This is completely unacceptable and I'm extremely upset.'”
