Download Polymarket Order Book Data
Download or query Polymarket order book data with historical bid/ask depth, snapshots, and resolved market metadata.
Download Polymarket order book data is a high-intent workflow for traders and researchers who need offline analysis, reproducible notebooks, or local backtesting. The useful export is not just price history. It should include bid depth, ask depth, timestamps, and market resolution details.
What to Download
- Market metadata with slug, coin, timeframe, open time, close time, and outcome.
- Historical snapshots at sub-second or strategy-relevant resolution.
- Full bid and ask levels for both outcome tokens.
- Reference prices and settlement metadata for evaluation.
API First, Export When Needed
PolyHistorical is API-first, which is better for iterative filtering by coin, market type, and time window. For heavier research, teams can export the same snapshot data into CSV, JSON, Parquet, DuckDB, or warehouse tables.
