It offers tick-level orderbook history captured from its own nodes and indexed from the chain, with trade and price history going back to 2020 and an always-on recorder logging every orderbook event. Data can be aggregated to any resolution from raw ticks up to hourly, covering Polymarket, Kalshi, and Opinion, with additional reference data from Limitless, Predict.fun, and Binance. Users can quote a slice of data for free before paying, then download it as compressed Parquet files via signed URLs, with free re-downloads within 24 hours. On the real-time side, Predexon runs a mempool-aware WebSocket that pushes Polymarket trades, prices, and orderbook updates up to five seconds before they confirm on Polymarket's own real-time data service, spread across seven channels with a single message schema and flat pricing. Beyond raw data, Predexon provides wallet analytics, PnL tracking, smart-money signals, and leaderboards computed directly from on-chain activity rather than scraped interfaces. A REST API covers markets, trades, orderbooks, wallets, and leaderboards through one key across venues, with Python, TypeScript, and cURL examples for getting started.
