Terms of use. The Fear & Greed API is for personal and single-product use. Redistribution or resale of the raw data is not permitted.
Yes. The free plan needs no card and does not expire. It covers the Fear and Greed Index, core market data and the earnings calendar, with a 90 day historical lookback and 300 requests per day.
Plus includes 3,000 API requests per day, ten times the Free allowance, a 365 day historical lookback, every site theme and font, and access to screeners, stock maps, chart metrics, 13F filings and ETF holdings.
Pro includes everything in Plus, removes the historical lookback window, raises the limit to 50,000 requests per day, and adds gamma exposure, implied move, supply chain and catalyst endpoints, plus CSV bulk exports and MCP server support.
Every request carries your key as a bearer token in the Authorization header. Keys are issued per account and can be rotated at any time.
The same pipelines that power the site itself: the Fear and Greed Index and its indicators, SEC 13F filings, options chains for gamma and implied move, and market data for prices and fundamentals.
No. The API is licensed for personal and single-product use. Reselling or republishing the raw data is not permitted.
Cancel at any time. Paid access continues to the end of the billing period, then the key drops back to free tier limits rather than being disabled.
