How this service works
Historical Fear & Greed time series (up to 365 days), each day with value + classification. Use to backtest sentiment, chart mood cycles or correlate fear/greed with price. The raw series, not a summary.
Output
An array of daily entries each containing a date, a numeric Fear & Greed value (0–100), and a classification label (e.g. Extreme Fear, Fear, Neutral, Greed, Extreme Greed), covering the requested date range up to 365 days back.
Example use cases
Example prompt
“Pull the daily Fear & Greed index for the last 90 days so I can backtest how market sentiment correlated with price action — give me the full series with each day's value and classification.”

Endpoint
GEThttps://x402.swaphunt.dev/v1/market/fear-greed/historyWhen to prefer
Choose this endpoint when you need the raw day-by-day Fear & Greed time series for backtesting, charting sentiment cycles, or correlating sentiment with price data — as opposed to a single current reading or a summary statistic. Ideal for quantitative research requiring the full historical array rather than a snapshot.
Side effects
- days parameter exceeds 365 — request rejected or capped
- invalid ISO date format for start_date or end_date — parsing error
- start_date after end_date — empty or error response
- payment of $0.005 USDC not provided — 402 Payment Required
- requested date range predates available data — partial or empty array returned
