How this service works
Data and AI services via x402 payment protocol
Output
The endpoint returns a JSON object containing the sentiment classification of the input text, likely indicating polarity (positive, negative, neutral) and potentially a confidence score or numeric sentiment value.
Example use cases
Customer review sentiment scoring
“Analyze the sentiment of this product review for me: 'Absolutely love this blender — it's powerful, quiet, and easy to clean. Best purchase I've made all year.' Is it positive, negative, or neutral?”
Social media comment moderation
“I need to know the sentiment of this tweet before we respond to it: 'Your customer service team kept me on hold for 45 minutes and then hung up. Never buying from you again.' What's the tone?”
Support ticket triage by tone
“Can you check the sentiment of this support ticket message so I can prioritize it: 'I've been waiting three weeks for my refund and nobody has responded to my emails. I am extremely frustrated.'”

Choose this endpoint when you need a quick, pay-per-use sentiment classification via the x402 micropayment protocol without a subscription or API key. Ideal for low-volume or on-demand sentiment scoring in crypto-native or agent-based workflows where USDC micropayments are already in use.
Side effects
- Missing or empty 'input' parameter returns a 400 error
- Payment not attached or insufficient USDC triggers a 402 Payment Required response
- Very long input strings may be truncated or rejected
- Non-English text may produce inaccurate or undefined sentiment results
- Network timeouts on the Railway-hosted deployment
