EODHD Real-Time Data API (WebSockets)

EODHD Real-Time Data API (WebSockets) is a websocket from EOD Historical Data (EODHD) providing stocks & equities data. EODHD's Real-Time Data API streams live US equity trades and quotes, plus forex and crypto, over persistent WebSocket connections with sub-50ms transport latency. A Polymarket bot would use it to track live last-trade and bid/ask prices for tickers like AAPL/TSLA/MSFT to settle or hedge "will X close above $Y" price markets in real time.
