## 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 api-syraa-fun-abf06fc2
```

Example prompt: What's the current sentiment for BTC — is the market feeling bullish or bearish, and how confident is the signal?

## When to prefer this

Use this endpoint when you need fast, paid-quality sentiment analysis specifically for crypto tickers or general market text, and you want a structured score plus confidence level rather than a raw NLP output. Prefer it over general-purpose NLP APIs when the domain is financial/crypto market chatter and when you are operating within a USDC micropayment workflow.

## Known failure modes

- Missing required 'input' parameter returns a 400 error
- Invalid or unsupported ticker symbol may return null or low-confidence results
- Payment not fulfilled (402) if USDC payment via x402 is not completed
- Service unavailable or timeout on high-load periods
- General text with no clear sentiment may return neutral with low confidence
