API & Developers

Polymarket Historical Price Data and Price History API

Use PolyHistorical for Polymarket historical price data, Polymarket price history, historical prices API workflows, and CLOB price-history research.

Polymarket historical price data is the time series of market prices, probabilities, and bid/ask quotes that lets you analyze past market behavior. PolyHistorical stores price history together with full order book depth so price moves can be tied back to liquidity.

Polymarket Price History

Polymarket price history is useful for charts, probability curves, signal testing, and historical research. For execution-aware backtesting, pair it with bid/ask depth so your simulator does not assume every trade filled at the midpoint.

Polymarket Historical Prices API

The snapshots endpoint acts as a Polymarket historical prices API and a Polymarket price history API. Developers can request market snapshots, then extract midpoint, best bid, best ask, and outcome-token prices.

Docs and CLOB Price History Queries

If you are looking for Polymarket API historical prices docs, Polymarket CLOB prices-history API, Polymarket CLOB API historical prices, or Polymarket subgraph historical prices, the main limitation is that live CLOB and subgraph sources are not designed as complete historical archives. PolyHistorical keeps the historical snapshots separately for repeatable analysis.
