## 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 neurofi-crypto-sentiment-analysis-4ad636c2
```

Example prompt: What's the current market sentiment around Bitcoin right now — is it bullish, bearish, or neutral?

## When to prefer this

Use this endpoint when you need real-time, AI-synthesized sentiment for a specific crypto asset or topic, especially when you want signals derived from live web content rather than static historical data. Prefer this over generic sentiment APIs when you need crypto-domain-specific analysis augmented by LLM reasoning.

## Known failure modes

- Unknown or unsupported topic returns empty or low-confidence sentiment
- Tavily web search rate limit or unavailability causes degraded analysis
- Payment not processed (402) returns no data
- Malformed topic parameter returns error
- LLM inference timeout on complex or trending topics
