What This Skill Does
Fetches the Alternative.me Crypto Fear & Greed Index, a daily 0-100 score that classifies retail market sentiment as Extreme Fear, Fear, Greed, or Extreme Greed. The API requires no authentication or API keys.
Free, unauthenticated access to a widely-cited sentiment signal removes setup friction from daily pre-analysis checks.
When to use it
- Anchoring sentiment before analyzing crypto news headlines
- Checking market psychology before entering a long position
- Assessing correction risk during a euphoric rally
- Identifying potential capitulation signals in a downturn
- Supplementing on-chain flow analysis with retail sentiment context
