Marketlens
FreemiumData platform providing tick-level historical Polymarket order book and trade data through a Python SDK and backtesting REST API for quantitative research and strategy development.
What Marketlens does
Marketlens captures every Polymarket order book change the moment it happens. Full L2 depth, tick-by-tick, every change recorded. Full order book history, executed trades, OHLCV candles, and underlying asset prices are available via REST API, Python SDK, or bulk Parquet export.
Backtest your bot against historical order books at millisecond resolution. Fills account for queue position, latency, and slippage.
We track binary, multi-strike, barrier, and macro markets across crypto, equities, FX, commodities, indices, and rates. Examples include BTC, ETH, SOL, and XRP up or down (5m, 15m, daily), weekly BTC close ranges, "Will BTC hit $X" barriers, and FOMC rate decisions. Each repeats on a fixed schedule, so you can backtest across many past runs of the same market.
Free tier: 2,000 requests/day with full data access.
