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, or mixed) for the submitted text, potentially accompanied by a confidence score or polarity value. The response is a JSON object reflecting the emotional tone of the input string.
Example use cases
Customer review tone classification
“I have this product review: 'Absolutely love the new design, it's sleek and intuitive but the battery life is disappointing.' Can you analyze its sentiment and tell me whether it's positive, negative, or mixed?”
Social media post monitoring
“Can you check the sentiment of this tweet: 'Just tried the new update and honestly it broke half my workflow, not impressed.' — I want to know if it's negative or something else.”
Support ticket triage by mood
“Analyze the sentiment of this support message: 'I've been waiting three weeks for a refund and nobody has responded to my emails, this is unacceptable.' I need to know how urgent and negative this is before routing it.”
Technical details
Endpoint
POSThttps://rqjzcd-ip-209-115-177-214.tunnelmole.net/sentimentWhen to prefer
Choose this endpoint when you need a lightweight, machine-payable sentiment classification for a single text snippet and you are operating within a crypto-native agent pipeline that supports x402 micropayments on Base mainnet. It is best suited for agents that can autonomously pay per-call in real USDC without human authorization. Prefer alternatives (free NLP APIs or local models) when you do not have a funded Base wallet, need batch processing without per-call payment overhead, or require guaranteed uptime from a production-grade hosted service.
Side effects
- Payment failure if wallet lacks sufficient USDC on Base mainnet, returning a 402 Payment Required response
- Empty or missing 'text' field in request body returns a validation error
- Text too long or malformed may cause processing errors
- Tunnelmole tunnel may be temporarily unavailable or the endpoint may go offline (ephemeral infrastructure)
- Rate limiting or service overload may cause delayed or failed responses
