01 · Overview

What is PolymarketData?

PolymarketData stores historical time series and L2 snapshots behind a structured API and export workflow. Best for: Developers who need hosted historical time series and L2 snapshots for Polymarket research, exports, and backtests without maintaining their own collectors. Less suitable for: Users needing multi-venue normalization or trading execution. Key limitations: Historical start dates and field coverage vary, so verify the exact market and interval before designing a backtest.
