Introduction
TRADRR is a data layer for Polymarket crypto prediction markets. Historical order books, trades, and resolved Up-or-Down markets across BTC, ETH, SOL, XRP, DOGE, BNB and HYPE — joined with Binance spot, exposed over a REST API and as bulk Parquet downloads.
What's in the box
- Resolved markets— every Up-or-Down market we've tracked, with start price, end price, winner, and the full book history per side.
- L25 order book snapshots — 25 levels of bid/ask depth, captured at microsecond resolution.
- Top-of-book quotes and trades — every quote update and every executed fill, per market and outcome.
- Binance spot overlay — each market joined to second-resolution Binance trades, so you can attribute price moves to the underlying.
Three ways to consume it
- REST API — single-market reads, ideal for live dashboards and ad-hoc analysis. Start with the quickstart.
- Bulk Parquet downloads — full historical pulls served from Cloudflare R2 with zero egress cost. See datasets.
- Python SDK — strategy decorator, backtest runner, and a paper-trading mode against live books. Preview.
Coming soon
The Python SDK is in active development. The REST API and bulk downloads are live today — everything you can do with the SDK, you can already do with a few HTTP calls.
Next steps
