## 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-2e749419 -d '<json body>'
```

Example prompt: Can you analyze the sentiment of this customer review: 'The product arrived quickly but the packaging was damaged and customer support was unhelpful'? Tell me if it's positive, negative, or neutral.

## When to prefer this

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.

## Known failure modes

- 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
