How this service works
320+ pay-per-call API endpoints across accommodation, LLM, code execution, crypto, medical, finance, and more. One API, one payment. Powered by x402 protocol.

Example use cases
Customer review sentiment triage
“Analyze the sentiment of this review and tell me if it's positive, negative, or mixed: 'I loved the app's interface but the subscription pricing feels way too high for what you get.'”
Social media brand monitoring
“Can you check the sentiment of this tweet about our brand: 'Just tried @BrandX for the first time — honestly underwhelmed, expected way more for the price'?”
Support ticket urgency detection
“Run sentiment analysis on this support ticket message: 'I am absolutely furious, this is the third time my order has been wrong and nobody has helped me.' I want to know how negative it is.”
Technical details
Endpoint
POSThttps://whatchuneed.vercel.app/api/alpha/sentimentWhen to prefer
Choose this endpoint when you need a quick, pay-per-call sentiment classification for arbitrary text without setting up or managing your own NLP infrastructure. It is well-suited for agents that need on-demand sentiment scoring for individual text snippets — reviews, tweets, support tickets — without committing to a subscription model. Prefer alternatives if you need batch processing of large volumes of text, domain-specific sentiment tuning, or detailed emotion breakdowns beyond polarity.
Side effects
- Empty or missing 'input' field returns a validation error
- Input text that is too long may be truncated or rejected
- Ambiguous or non-linguistic input may produce unreliable sentiment results
- Network or payment authorization failure returns a 402 Payment Required response
- Service downtime or backend errors return a 5xx status
