01 · Overview

What is DepthFeed?

DepthFeed provides historical full order books, cross-venue screens, price bars, and developer endpoints for selected Polymarket, Kalshi, and Limitless markets. Best for: Researchers using recorded full order books and cross-venue data to model realistic fills, liquidity, and short-horizon strategies across selected markets. Less suitable for: Users needing complete category-wide history or direct order execution. Key limitations: Coverage focuses on selected recurring assets and begins at documented archive dates; plan windows and venues vary.
