## 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 crypto-fear-greed-news-sentiment-index-65202fe8
```

Example prompt: What's the current crypto market sentiment right now — is it bullish, bearish, or neutral? Blend the Fear & Greed index with the latest news headlines, and focus on Bitcoin if you can.

## When to prefer this

Choose this endpoint when you need a single, pre-blended sentiment signal that combines both market-wide Fear & Greed momentum and news-headline tone in one call, rather than querying separate sentiment and news APIs and merging them yourself. Ideal for trading agents, portfolio monitors, or daily briefing bots that want a fast, opinionated bullish/bearish/neutral label with minimal post-processing. Prefer the sibling `timing-fng` endpoint if you only want the raw Fear & Greed index with trend data and no news blending.

## Known failure modes

- Upstream alternative.me API unavailable — Fear & Greed data missing or stale
- No relevant RSS headlines found for a niche coin query — news sentiment may default to neutral
- Invalid or unrecognized coin symbol — may return general market sentiment instead
- Rate-limit or payment failure (x402) — 402 response requiring valid USDC micropayment
- Stale data if RSS feeds are temporarily down — sentiment may lag real-time events

## How this service works

Crypto Fear & Greed Index: the market Fear & Greed value, classification and trend, blended with aggregated crypto news-headline sentiment into one bullish/bearish/neutral score, optionally focused on a coin or query. Data by alternative.me (attributed) + curated RSS headlines.

## Output

A blended sentiment assessment combining the numeric Fear & Greed Index value and classification (e.g. Fear, Greed, Extreme Greed) with trend direction and aggregated crypto news-headline sentiment, producing a single bullish/bearish/neutral label. May include the underlying Fear & Greed score, trend context, and news-derived signal, optionally scoped to a specific coin or query.
