How this service works
Market signal engine for AI agents and traders: Kronos forecasts blended with market data, volatility ranges, prediction-market odds and sentiment into one JSON fact list. Crypto live; stocks, forex rolling out. Pay per call via x402.
Output
A JSON object containing: the market symbol, a directional forecast (UP or DOWN), a confidence rating (e.g. LOW/MEDIUM/HIGH), an expected price range array [low, high], the forecast horizon end timestamp, an as-of timestamp, and whether the band is calibrated. Covers BTC-USD and ETH-USD in real time.
Example use cases
Crypto trading decision support
“Before I make a trade, can you pull the QuantX402 signal for BTC-USD and tell me whether it's trending up or down, how confident the model is, and what price range to expect?”
Automated ETH portfolio rebalancing trigger
“Check the current market signal for ETH-USD — if direction is UP with MEDIUM or HIGH confidence, flag it so I can consider adding to my position.”
Daily crypto market briefing
“Give me this morning's market outlook for Bitcoin: what direction is it predicted to move, what's the confidence level, and what's the expected price range for the day?”

Endpoint
GEThttps://quantx402.app/api/v1/basic?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a fast, pay-per-call (no subscription) blended crypto market signal that combines forecasting, sentiment, volatility, and prediction-market odds in a single JSON call. Prefer it over raw price feeds when you want an interpreted directional signal with confidence and range, not just a spot price. Best for AI agents that need actionable trading context without building their own signal pipeline.
Side effects
- Unsupported symbol (only BTC-USD and ETH-USD currently live) returns an error or empty result
- Payment failure via x402 protocol blocks access
- Stale or uncalibrated band (band_calibrated: false) indicates the range estimate may be less reliable
- Rate limiting if wallet address not provided and free trial already used
- Network timeout if upstream market data sources are unavailable
