Could you build this?
Partial A unified REST/WebSocket wrapper around prediction market APIs is straightforward, but maintaining tick-level order book historical ingestion and cross-venue smart order routing requires serious low-latency data infrastructure.
What it would actually take: Built with Python/Rust, TimescaleDB or ClickHouse for tick-level storage, and WebSocket feeds to Kalshi and Polymarket (including Web3 signing/EVM interactions). The challenge lies in normalized cross-venue order matching algorithms, slippage calculation across different market maker styles, and recording massive sub-second tick feeds without dropping packets.
