How this service works
Crypto Fear & Greed Index: current reading (0-100, Extreme Fear to Extreme Greed) plus 7-day and 30-day sentiment trend (rising/falling/flat with the average and point change), not just a single snapshot number. Not ticker-specific. Data from alternative.me. $0.01/call.
Output
Returns the current Fear & Greed Index value (0–100 mapped to labels like Extreme Fear, Fear, Neutral, Greed, Extreme Greed), plus 7-day and 30-day sentiment trend summaries including the trend direction (rising/falling/flat), the average score over the period, and the net point change across the window. Optionally returns historical daily readings if a limit parameter is provided.
Example use cases
Daily crypto trading sentiment check
“Pull the current Fear & Greed Index for crypto and tell me whether sentiment has been trending more fearful or greedy over the last 30 days — I want to know the average score and how many points it's moved.”
Contrarian buy signal detection
“Is crypto sentiment in extreme fear territory right now? Give me today's Fear & Greed score and the 7-day trend so I can decide if this might be a contrarian buying opportunity.”

Technical details
Endpoint
GEThttps://www.x402financialdata.com/fear-greedWhen to prefer
Choose this endpoint when you need a real-time, market-wide crypto sentiment signal with trend context — not just a single number snapshot. Ideal for trading dashboards, contrarian signal detection, or periodic sentiment reporting workflows. Prefer over raw alternative.me API when you need the 7-day and 30-day trend analysis pre-computed in one call. Not suitable for ticker-specific sentiment or equity market sentiment.
Side effects
- Upstream alternative.me API unavailability may cause stale or missing data
- Invalid limit parameter type returns a validation error
- No ticker-specific filtering is supported — index is market-wide only
- Payment failure (insufficient USDC) returns a 402 error
