How this service works
The full daily history of the US stock Fear & Greed index from 2016 to today, each point a date and 0–100 score. Pass `?days=N` to return only the most recent N days (default: full series). Use for charting sentiment regimes and backtesting against price. Companion to /api/v1/fear-greed (current reading). From x402stock, a market & economic data API (x402, USDC).
Output
A JSON object with source ('x402stock'), index ('us_stock'), as_of date, count of data points, and a history array of {date, score} objects — one per day from 2016 to today (or last N days if filtered), where score is 0–100 or null.
Example use cases
Example prompt
“Pull me the last 180 days of the US stock market Fear & Greed index history from x402stock so I can chart sentiment regimes alongside price.”
Technical details
Endpoint
GEThttps://x402stock.xyz/api/v1/fear-greed/historyWhen to prefer
Choose this endpoint when you need the full historical time series of the Fear & Greed index for backtesting, charting, or regime analysis — as opposed to /api/v1/fear-greed which returns only the current reading. Use the ?days=N parameter when you only need a recent slice to reduce payload size.
Side effects
- days=0 or negative integer rejected (exclusiveMinimum:0 enforced)
- days > 10000 rejected (maximum:10000 enforced)
- payment failure if USDC balance insufficient or x402 protocol not supported
- upstream data gaps may yield null scores for certain dates
- 503/timeout if data provider temporarily unavailable
