About PolyOrderbooks
Historical Polymarket Data API
PolyOrderbooks is a historical market data API for developers, researchers, and quantitative traders working with Polymarket. It provides historical L2 order books, prices, liquidity metrics, and market data through a REST API and Python SDK. Developers can replay past bid/ask depth for backtesting, execution modeling, spread analysis, and market research instead of relying only on price history. A free tier and sample dataset are available.
