Api Endpoint

QuantX402

Signal Blend: one merged multi-source fact list per symbol: Kronos signal + market data (momentum, volatility range, invalidation check) with a stance and plain-English reasons, plus a prediction_markets block: nearest-dated prediction-market "above $X" market prices next to an experimental model view of our volatility-based range (not odds). News/sentiment inputs rolling out. Experimental. Not financial advice.
