Unified Schema

One schema for all platforms

Polymarket uses condition IDs and token pairs on Polygon. Kalshi uses event hierarchies and series tickers. We receive updates via WebSocket and normalize both into one clean, consistent data model in near real-time.

Python SDK — client.markets() returns typed models or a dataframe
REST API with filtering by platform, status, and date range
Direct SQL queries via ClickHouse on the markets table
Monthly Parquet file exports for bulk analysis
