How this service works
Sentiment classification: Verb-path alias of POST /v1/cheap-errand ($0.01 USDC). Same handler + payment terms; path defaults task=sentiment when body.task omitted. Cheap agent glue for buyer-supplied text. Base via x402. No API key.
Output
Returns a sentiment classification for the submitted text — typically a label such as positive, negative, or neutral, along with any confidence or metadata provided by the underlying model. The response reflects the emotional polarity of the input string.
Example use cases
Customer review sentiment triage
“I have a batch of customer feedback messages — can you classify this one as positive, negative, or neutral? Here's the text: 'I've been waiting three weeks for my order and no one responds to my emails. Absolutely furious.'”
Social media monitoring for brand tone
“Can you tell me the sentiment of this tweet about our brand: 'Just switched to @BrandX and honestly can't believe how smooth the onboarding was. Totally worth it!'”
Support ticket emotional escalation detection
“Analyze the sentiment of this support ticket so I know how urgently to escalate it: 'This is the fourth time I've had to contact support for the same issue. I'm seriously considering canceling my subscription.'”

Endpoint
POSThttps://x402.hydratrader.ai/v1/sentiment?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need sentiment classification without managing API keys or subscriptions, and are comfortable paying $0.01 USDC per call via the x402 micropayment protocol. Ideal for agents that need on-demand, pay-as-you-go NLP without vendor lock-in. Best suited for single-text sentiment tasks rather than bulk batch processing.
