How this service works
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 Polymarket "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.
Output
A JSON object containing: stance (LEAN_UP, LEAN_DOWN, or NO_EDGE), symbol, odds_up (0–1 probability of price finishing higher), agreement (ALIGNED, OPPOSED, or MIXED between forecast and sentiment), sentiment value, invalidation_level (price level at which the signal is invalidated), and a reasons array of plain-English explanations.
Example use cases
Crypto trading decision support
“Before I place a trade, check the QuantX402 signal for BTC-USD and tell me if there's a bullish or bearish edge, what the odds are of it finishing higher, and where the invalidation level sits.”
Hourly Bitcoin signal monitoring
“Every hour, pull the 1h timeframe signal for BTC-USD and alert me if the stance flips from LEAN_UP to LEAN_DOWN or if NO_EDGE is returned — I want to track trend changes through the session.”
ETH sentiment and forecast alignment check
“Check the QuantX402 signal for ETH-USD and tell me whether the Kronos forecast is ALIGNED or OPPOSED to current market sentiment, and summarize the plain-English reasons it gives.”

Endpoint
GEThttps://quantx402.app/api/v1/signal?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a single pre-blended directional signal for Bitcoin or Ethereum that fuses AI forecasting (Kronos), volatility, prediction-market odds, and sentiment into one JSON payload — rather than calling separate data sources and synthesizing yourself. Ideal for trading bots, signal dashboards, or AI agents that need a quick actionable stance with an invalidation level, especially when you want Kronos-specific path probability (odds_up) rather than a generic price feed.
Side effects
- Unsupported symbol — only BTC-USD and ETH-USD are live; stocks/forex return errors or empty
- Payment not processed — x402 payment failure results in 402 response and no signal data
- Unsupported timeframe — only '1h' is currently accepted; other values are rejected
- Stale or unavailable market data — signal may return NO_EDGE when underlying data is insufficient
- Rate limiting — high-frequency callers may be throttled after repeated rapid calls
