BACKTEST POLYMARKET CRYPTO UP/DOWN MARKETS IN MINUTES
Click to view full sizePolyTest is a historical snapshots API focused on Polymarket crypto Up/Down prediction markets. It lets developers and traders pull timestamped market snapshots at sub-second resolution and replay full-depth orderbooks, including bid/ask levels, spreads, and volume. The product is positioned for fast strategy validation and bot development: users pick a supported market (BTC, ETH, SOL, XRP) and timeframe, fetch data with a single API call, then backtest entry/exit logic or simulate market behavior using the historical orderbook. PolyTest includes a TypeScript SDK with typed integration to speed development workflows, including those assisted by AI coding tools. It also highlights performance and reliability metrics (low response latency and high uptime) and offers a free tier to start without a credit card.
