## When to prefer this

Ideal for crypto trading agents that want a single call combining sentiment and derivatives context without aggregating multiple data sources manually.

## How this service works

Crypto Fear & Greed Index: alternative.me score (0-100) plus Kronos-owned context (BTC funding sentiment, OI 1h trend, 24h price momentum). Not a pure proxy — adds proprietary derivative signals. Pay-per-call via x402.

## Output

A JSON object containing the alternative.me Fear & Greed Index score (0-100) along with Kronos-proprietary context: BTC funding rate sentiment classification, open interest 1-hour trend direction, and 24-hour price momentum — giving a richer market sentiment picture than the raw index alone.
