PMXT is a unified API and SDK (Python and TypeScript) for prediction markets, modeled after CCXT, covering venues like Polymarket, Kalshi, Limitless, Smarkets, and Probable. It provides market data, OHLCV history, cross-venue market/event matching, and trading in both hosted and self-hosted modes.

Use cases

  • trade polymarket and kalshi from one codebase
  • find price discrepancies across prediction markets for arbitrage
  • fetch historical ohlcv candlestick data for prediction markets
  • backtest trading strategies on prediction market data
  • match the same event across different prediction market venues
  • build a prediction market trading bot
  • compare odds across prediction market platforms

When to choose

  • you need a single unified API across multiple prediction market venues instead of per-venue integrations
  • you want cross-venue arbitrage or market matching out of the box
  • you want CCXT-style SDK ergonomics for prediction markets in Python or TypeScript
  • you need historical OHLCV data and hosted catalog search with one API key

When to avoid

  • you only trade a single venue and prefer direct venue-native APIs with full control
  • you need a fully free service without any hosted dependency - hosted features require an API key and paid plans for volume
  • you need exchanges outside the supported prediction-market venues
  • your use case is crypto spot/derivatives trading rather than prediction markets - use CCXT instead
