Get Polymarket Price History
Retrieve price history for a Polymarket market. Each record shows the price at a point in time derived from trades.
What you get:
- Exchange identifier
- Condition ID (market identifier)
- token_id: The token identifier for this price point
- outcome: The outcome label for this token (e.g., “Yes”, “No”, or a named outcome like “EDward Gaming”)
- Price (as decimal, e.g., 0.992 = 99.2%)
- Timestamp
Important: This endpoint requires the condition_id (hex string starting with 0x), NOT the standard poly_id.
Use cases:
- Build price charts
- Analyze price movements over time
- Track market sentiment
- Backtest trading strategies
