PMXT

PMXT is a developer library that provides a unified, CCXT-style interface for trading on multiple prediction markets such as Polymarket and Kalshi. It aims to give quantitative traders, market makers, and analytics engineers a single, consistent API for placing orders, fetching markets, and managing positions across different prediction market venues.

Prediction markets each expose their own APIs, authentication schemes, and data models, which makes it painful to build cross-exchange strategies or analytics. pmxt abstracts these differences behind a common interface, similar to how CCXT standardizes access to centralized and decentralized crypto exchanges. This lets teams focus on strategy logic, risk management, and analytics instead of writing and maintaining multiple exchange-specific connectors.

The library is best suited for developers building systematic trading strategies, arbitrage bots, or research pipelines that need to compare or trade contracts across several prediction markets. Integration typically involves installing the package from the GitHub repository, configuring API keys for supported venues, and then using a standardized set of methods for market discovery, order placement, and account queries. Because it follows the CCXT mental model, teams already familiar with that ecosystem can adapt quickly.

While the repository does not yet expose detailed documentation in the README, the intent is clear: provide a composable, exchange-agnostic layer for prediction market connectivity. Teams can start by cloning the GitHub repo, exploring the source to see supported exchanges and method signatures, and wiring pmxt into their existing trading or analytics stack. As the ecosystem of prediction markets grows, pmxt can serve as a central integration point, reducing ongoing maintenance costs and enabling faster experimentation with new venues.
