## 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 whatchuneed-sentiment-analysis-0be5438b -d '<json body>'
```

Example prompt: Can you analyze the sentiment of this customer review: 'The delivery was extremely fast but the product quality was disappointing — not what I expected at all'?

## When to prefer this

Choose this endpoint when you need a pay-per-call sentiment analysis with no subscription or API key setup, and when you're already using the whatchuneed ecosystem for other utility endpoints. Ideal for low-volume or sporadic sentiment checks where per-call pricing at $0.03 USDC is cost-effective compared to subscription NLP services.

## Known failure modes

- Empty or missing 'input' field returns a validation error
- Extremely long input text may be truncated or rejected
- Non-English text may produce less reliable sentiment results
- Network timeouts or server errors return a failed status
- Payment failure via x402 protocol blocks the request entirely
