PolyBackTest

PolyBackTest provides historical Polymarket snapshots, order-book data and testing workflows with emphasis on short-duration crypto markets. Best for: Researchers modeling fills and strategy behavior on supported market intervals. Less suitable for: Users who need live execution or complete history for every Polymarket category. Key limitations: Asset, interval and archive coverage vary by plan; backtests remain sensitive to fees, queue position, latency and fill assumptions. Free access is limited to recent BTC markets, a 31-day window and 1 request/second. Paid configurations add ETH/SOL and selected history/rate limits. The 180-day shared configuration starts at $69.90/month for 10 RPS/300 RPM; this is not the minimum price of every paid configuration. Legacy 150-day plans are closed to new purchases. Entitlement is not proof that a market was recorded for the entire period.
