Example Usage

// WebSocket connection for real-time prices
const ws = new WebSocket('wss://stream.kicks.dev/prices');

ws.onmessage = (event) => {
  const {
    model,
    retailPrice,
    retailStock,
    resaleAsk,
    resaleBid,
    demandScore,
    updated
  } = JSON.parse(event.data);
  
  // Agent immediately processes new price data
  agent.evaluateOpportunity({
    model,
    retailPrice,
    retailStock,
    demandScore
  });
};
