Multi-venue vs Polymarket-specialized
Predexon covers Polymarket, Kalshi, Limitless, Opinion, Predict.fun, Binance, and Dflow with cross-venue search, smart money, and live feeds on higher tiers.
PolyOrderbooks narrows to Polymarket crypto with aligned prices, metrics, and L2 over REST — smaller surface area for crypto backtests.
Historical data and order books
Predexon documents ms-resolution orderbooks via REST plus tick Parquet. Core market data, historical trades, historical orderbooks, and pricing endpoints are unlimited on the Free plan; WebSocket and smart-wallet routes are gated on paid tiers.
PolyOrderbooks offers 1-second capture with query resolution down to 1s on paid plans via /markets/{slug}/books and the Python SDK.
When each may be a better fit
Predexon — multi-venue research, live feeds, wallet analytics, tick replay. PolyOrderbooks — Polymarket crypto L2 with simple REST and published tier pricing.
FAQ
What is Predexon?
Predexon is a prediction-market data layer with REST and WebSocket APIs across Polymarket, Kalshi, Limitless, Opinion, Predict.fun, Binance, and more — plus wallet analytics and tick Parquet downloads.
Does Predexon have historical order books?
Yes — Predexon documents GET /v2/polymarket/orderbooks and tick-level orderbook Parquet as separate products.
Predexon vs PolyOrderbooks — scope or focus?
Predexon is broader: multi-venue markets, wallets, smart money, and live feeds. PolyOrderbooks is narrower: a Polymarket crypto historical archive with aligned prices, metrics, and L2 over REST.
Does Predexon require a paid plan for historical data?
No — Predexon documents unlimited core market data, historical trades, historical orderbooks, and pricing endpoints on the Free plan. Dev ($49/month) and higher tiers unlock premium routes such as WebSocket and wallet analytics, not core historical REST.
