Platform & data
Is there a free API for crypto indicator data?
Yes — our public data API serves daily indicator readings (RSI, MACD, SuperTrend, moving-average posture, Bollinger position, ATR) for 50 coins, historical buy-and-hold outcomes per entry year, and the monthly Crypto Overfitting Index, all as JSON with no API key and no signup. Values are computed by the same engine code that runs our backtests.
The only requirement is attribution: a visible link to noonbarbari.xyz wherever the data is displayed (CC BY 4.0). Responses are cached for an hour, which is also the polite polling ceiling.
The fastest answer is a test
Most 'does X work?' questions take a minute to answer empirically — on real data, with an out-of-sample check, free.
