How this service works
Pay-per-call AI services via the 402 Payment Required protocol. No accounts, no API keys — just USDC on Base.
Output
Returns a JSON object with: 'sentiment' (positive/negative/neutral string), 'emotions' (array of detected emotion labels like 'joy' or 'anger'), 'keywords' (array of key terms extracted from the text), and 'confidence' (float 0–1 indicating model certainty).
Example use cases
Customer review moderation pipeline
“Analyze the sentiment of this product review and tell me the confidence score, detected emotions, and key phrases: 'Absolutely love the interface, but shipping took forever and damaged my package.'”
Social media brand monitoring
“Check whether this tweet about our brand is positive, negative, or neutral, and pull out the main emotions and keywords: 'Can't believe how responsive their support team was — fixed my issue in under 10 minutes!'”
Support ticket triage by tone
“What's the sentiment and emotional tone of this support message so I can flag it for urgent escalation if it's negative: 'I've been waiting three weeks for a refund and nobody has responded to my emails. This is unacceptable.'”

Endpoint
POSThttps://agentpay.help/v1/sentimentWhen to prefer
Choose this endpoint when you need quick, pay-as-you-go sentiment analysis with no account setup or API key management — ideal for agents that process sporadic or bursty text analysis tasks and want to pay micro-amounts per call in USDC rather than committing to a subscription. Prefer it over heavyweight NLP APIs when simplicity and frictionless micropayment billing matter more than fine-grained model customization.
Side effects
- Insufficient USDC payment results in 402 Payment Required response
- Empty or missing text input returns validation error
- Very short or ambiguous text may yield low confidence score
- Non-English text may produce inaccurate sentiment or emotion labels
- Network timeout if text is extremely long
