Kronos Quant Signal API

Multi-asset financial intelligence: crypto, commodities, and pre-market equities. Multi-timeframe price-path forecasts with calibrated conformal prediction intervals.

Key Features

32 endpoints — predictions, trading signals, regime detection, risk metrics, accuracy/calibration data, agent signals, market briefs, and more.
x402 payment protocol — pay per request with USDC on Solana or Base. No API key required. Prices from $0.001 to $0.05 per request.
8 free endpoints — catalog, sample forecasts, accuracy previews, conviction signals, risk state, benchmark preview, and composite preview.
Multi-asset coverage — BTC, ETH, SOL, XRP, BNB, LTC, AAPL, and on-demand discovery for any Gate.io symbol (crypto, stocks, forex, metals, commodities, indices).
Multi-timeframe forecasts — 5m, 15m, 1h, 4h, 1d with horizons from 6h to 14d.
Calibrated conformal prediction — probabilistic forecasts with calibrated confidence intervals, not just point estimates.

Authentication

No API key required. Paid endpoints return HTTP 402 with payment details (amount, network, payTo address). Pay with USDC on Solana or Base via the x402 protocol. Free endpoints work without payment.
