How this service works
Lightweight text utilities for AI agents: key-sentence digest, sentiment label, and entity extraction (email, URL, EVM/Solana addresses). Pay-per-request in USDC on Base and Solana via x402. No API keys, no accounts, no signup.
Output
A JSON object containing a label field ('positive', 'negative', or 'neutral'), a score (float 0–1 indicating polarity strength), and a hits object with pos and neg integer counts representing how many positive and negative signals were detected in the text.
Example use cases
Triage negative support tickets
“Check the sentiment of this incoming support message and flag it if it's negative: 'I've been waiting three weeks for my refund and nobody has responded to my emails.'”
Monitor product review tone
“Analyze the sentiment of this product review for me: 'Battery life is fantastic and the screen is gorgeous, but the price feels a bit steep for what you get.'”
Evaluate social media comment
“Is this tweet about our brand positive or negative? 'Just switched to a competitor after years of loyalty — couldn't be more disappointed with the recent changes.'”

Endpoint
GEThttps://kassa-402.annushka1190.workers.dev/v1/sentimentWhen to prefer
Choose this endpoint when you need fast, pay-as-you-go sentiment classification with no account setup or API key management, especially in agent pipelines that handle USDC micropayments via x402. Ideal for lightweight per-message sentiment checks rather than bulk batch analytics or deep multi-dimensional emotion analysis.
Side effects
- Missing or empty 'text' query parameter returns a 400 error
- Payment not included or insufficient USDC amount returns a 402 Payment Required response
- Text too long may cause truncation or timeout
- Ambiguous or mixed-sentiment text may produce a low-confidence score near 0.5
