## 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 healthcare-sentiment-indexer-mcp-52535b58 -d '<json body>'
```

Example prompt: Can you analyze the sentiment of this patient review and tell me if it's positive or negative: 'The nursing staff was incredibly attentive but the wait times were unreasonably long and frustrating'?

## When to prefer this

Choose this endpoint when you need a fast, binary (positive/negative) sentiment classification specifically tuned for healthcare text such as patient reviews, clinical notes, or medical feedback. Best suited for high-volume triage pipelines where a simple boolean output is sufficient and nuanced multi-class sentiment scores are not required.

## Known failure modes

- Missing required 'text' field returns a validation error
- Empty string input may return unpredictable boolean result
- Very long text strings may exceed input limits and fail
- Non-healthcare or ambiguous text may yield unreliable boolean classification
- Payment failure via x402 protocol prevents execution
