How this service works
Machine-payable NLP micro-services: sentiment, entity extraction, summarization, report, batch. Paid per call in REAL USDC on Base mainnet.
Output
Returns a sentiment classification (e.g. positive, negative, neutral) and likely a confidence score or polarity value for the analyzed text. The response is delivered after a real USDC micropayment is settled on Base mainnet via the x402 protocol.
Example use cases
Customer review tone monitoring
“Check the sentiment of this review left on our product page: 'Absolutely love this blender — it's quiet, powerful, and easy to clean. Best purchase I've made this year!' Is it positive, negative, or mixed?”
Social media comment triage
“I need to know the sentiment of this tweet before I respond to it: 'Waited 45 minutes on hold and nobody helped me. This company's support is an absolute joke.' Is the customer angry or just frustrated?”
News headline sentiment scoring
“Can you tell me whether this headline reads as positive or negative sentiment: 'Fed signals possible rate cuts as inflation cools, boosting market confidence'?”

Choose this endpoint when you need pay-per-call, machine-payable sentiment analysis with no subscription required — ideal for AI agents that autonomously pay per inference using USDC on Base mainnet via x402. Best for sporadic, unpredictable usage patterns where a subscription model would be wasteful, or for agent pipelines that need crypto-native billing.
Side effects
- Empty or missing 'text' field in the request body returns a validation error

- Text that is too long may be truncated or rejected depending on model limits
- Tunnelmole tunnel downtime may cause connection timeouts or 502 errors
