## 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 minia2a-x402-sentiment-87e3f34d
```

Example prompt: Can you run sentiment analysis on this customer review and tell me whether it's positive, negative, or neutral: 'The product arrived on time but the packaging was damaged and the instructions were confusing.'

## When to prefer this

Choose this endpoint when you need a quick, low-cost ($0.01 USDC) sentiment classification for a single text input and are already operating in an x402 payment-enabled agentic stack. It is suitable for lightweight, real-time sentiment checks on reviews, tickets, or social posts where a pay-per-call model is preferred over a subscription API.

## Known failure modes

- Missing 'input' field returns a validation error
- Empty or too-short text may return ambiguous or null sentiment
- Unsupported text encoding or language may yield incorrect classification
- Payment failure via x402 protocol blocks the request entirely
- Rate limiting or service unavailability returns a 402 or 5xx error
