Kronos Crypto Data & Forecasts.

GET https://kronossignals.com/api/v1/funding-extremes ↗

Crypto funding-rate extremes screener: scans all 16 perpetual futures markets (BTC/ETH/SOL/BNB/XRP/DOGE/ADA/AVAX/LINK/DOT/LTC/TRX/BCH/ATOM/NEAR/APT). Uses z-score (30-day baseline) to identify statistically extreme funding: |z|≥2 = extreme, |z|≥3 = critical. Returns only assets clearing the threshold. Real-time from Kronos market_signals (Bybit data). Pay-per-call via x402.
