Api Endpoint

api.n0brains.com

Historical market-state analogs: k-nearest past market states to right now (SPX/NDX momentum, VIX level + term structure, dollar, yield curve) with what SPX, NDX and BTC actually did over the following 1d/5d — median, quartiles, hit-rate. 'When did the market look like this before and what happened next.' Deterministic distributions, conditioning context not a prediction. Not financial advice.
