## 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 allthebot-sentiment-analysis-b6c3c54a
```

Example prompt: Can you analyze the sentiment of this review and tell me whether it's positive, negative, neutral, or mixed, along with a confidence score and a short reason: 'The product arrived quickly but the packaging was crushed and customer support never replied to my email.'

## When to prefer this

Choose this endpoint when you need fast, per-call sentiment scoring with a human-readable explanation, a numeric -1 to +1 score, and a confidence value — especially for multilingual reviews, tweets, or support tickets where explainability matters. Prefer it over bulk ML pipelines when you need pay-per-call pricing with no infrastructure setup.

## Known failure modes

- Missing 'text' query parameter returns an error
- Text exceeding 4000 characters may be rejected or truncated
- Non-UTF-8 or malformed text may cause unexpected classification
- Very short or ambiguous input may yield low confidence scores
- Network or payment failure returns a 402 or 5xx error
