Engineered for Trading and Research

API access is our primary product for integrating Polymarket historical data into research and trading systems, with export and direct-delivery options for batch workflows.

API-First Access

Access series, events, markets, prices, metrics, and order books over API for reproducible quantitative research and production trading systems.

Complete Historical Model

Query the full hierarchy of series, events, and markets with historical market state, resolution outcomes, and metadata for backtests and analytics.

Exports and Direct Delivery

Beyond API calls, we support recurring exports and direct delivery so teams can run large historical pipelines without changing internal tooling.
