Problem
Prediction market developers face fragmented access across 15+ venues, each with its own authentication, pagination, field names, and rate limits. Building cross-market tools requires normalizing disparate APIs, maintaining data pipelines for market resolution and re-pricing, and constantly updating integrations when venues change endpoints—creating significant engineering overhead and slow time-to-market.
Solution
PMXT provides a unified SDK and API that abstracts the complexity of connecting to multiple prediction markets, including Polymarket, Kalshi, Limitless, Smarkets, and 12 more venues. The platform offers hosted mode with a shared catalog and cross-venue search, or self-hosted mode via pmxt-core for direct venue access. Developers write the same method names and get unified response shapes across venues where capabilities are supported. The Router layer enables cross-venue intelligence, linking identical markets and surfacing price discrepancies, while a Smart Order Router handles best execution across venues.
Target Audience
Primary users are software developers, quantitative traders, and analytics platforms building prediction-market trading bots, research tools, and arbitrage systems that require multi-venue access without per-venue integration work.
