## 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 saylor-innovations-crypto-news-sentiment-1b945b2c
```

Example prompt: What's the current crypto market vibe — pull the Fear & Greed index and the 24-hour news sentiment so I can see whether the market is fearful or greedy right now.

## When to prefer this

Choose this endpoint when you need a quick, combined snapshot of both the quantitative Fear & Greed index and qualitative news mood in a single call, rather than querying separate sentiment APIs. Ideal for trading bots, market dashboards, or AI agents that need to make decisions based on prevailing crypto market emotion without scraping multiple sources.

## Known failure modes

- Upstream Fear & Greed index provider unavailable — stale or missing fear_greed data
- News aggregation delay causing incomplete news_24h sentiment
- Payment validation failure via x402 returning 402 status
- Empty by_coin array if coin-level sentiment data is unavailable
- Timeout if external data sources are slow to respond
