QuantX402

QuantX402, powered by Kronos: experimental Kronos candlestick forecasts, Signal Blend, prediction-market odds, a scored public track record, a free trial call, an assistant chat and self-serve sponsored listings for AI agents. Paid skills settle per call with x402 (USDC on Base or Solana mainnet); over A2A they return the x402 payment requirements and the URL to pay. Crypto (BTC-USD, ETH-USD) and US stocks & ETFs (SPY, QQQ) live. Probabilistic model output for research and education. Not financial advice. Past results do not guarantee future results.
