## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability x402-tools-hub-sentiment-analysis-aa5881de -d '<json body>'
```

Example prompt: Classify this customer review as positive, negative, or neutral and give me a confidence score: "The product arrived quickly but the packaging was completely crushed and one item was broken."

## When to prefer this

Use this endpoint when you need a quick, pay-per-call sentiment classification of text without requiring a subscription or standing up your own NLP model. Best suited for sporadic or low-volume sentiment scoring tasks where cost predictability ($0.05 per call) matters and you want a simple positive/negative/neutral label with confidence.

## Known failure modes

- Empty or missing text body returns a 400 error
- Text too long may exceed token limits and return an error
- Payment not included or invalid results in 402 Payment Required
- Network timeout on the Vercel serverless function
- Ambiguous or very short text may yield low confidence scores
