## 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 x402-market-sentiment-analyzer-8a9c7fe0 -d '<json body>'
```

Example prompt: Analyze the market sentiment of this text for me: 'Q3 earnings beat expectations with record revenue growth, signaling strong investor confidence ahead of the holiday season.' Tell me whether it's positive, negative, or neutral and give me a confidence score.

## When to prefer this

Choose this endpoint when you need a fast, pay-per-call market sentiment classification on financial or market-related text without committing to a subscription. It is well-suited for AI agents that need to programmatically gauge bullish/bearish tone in news headlines, social posts, or analyst commentary, and it returns a machine-readable score alongside the label, making it easy to integrate into downstream decision pipelines.

## Known failure modes

- Empty or missing text input returns an error
- Malformed request body results in a 400 response
- Insufficient x402 payment balance causes a payment-required failure
- Very long text inputs may exceed processing limits
- Non-English or ambiguous text may yield lower-confidence scores
