Use this endpoint when you need historical price data for a specific prediction market event on a known exchange (Kalshi=4141, Polymarket=4137, Gemini=4008). Ideal for charting price movement, analyzing volatility, or backtesting signals on event contracts. Prefer this over volume or open-interest endpoints when the primary need is price (not trading activity or positioning).
