healthyKronos Crypto Data & Forecasts.
XRP price direction forecast. Composite model: EMA(20/50)/RSI(14)/MACD(12,26,9)/ATR(14) heuristic off Binance klines. Measured on predictions actually served: 49% directional over 500+ scored XRP forecasts — below our ~54% all-asset headline; verify per-asset at /api/stats (beta_accuracy). Returns up_prob, range_low/high, and accuracy_note. Pay-per-call via x402 on Base USDC. Live track record at /api/stats: ~54% hit over 15k+ scored forecasts, not a backtest.
