Could you build this?
Partial Aggregating publicly available REST/WebSocket APIs from prediction markets (e.g., Polymarket, Kalshi) into a unified dashboard is straightforward, but low-latency unified order execution and liquidity management require specialized trading infra.
What it would actually take: A unified prediction market API requires standardized schema translation layers across heterogeneous protocols (WebSockets, REST, and EVM/Solana smart contract transactions). The backend needs high-throughput message queues (Kafka or Redis Streams) to normalize real-time order books, manage signing keys across chains and CFTC-regulated platforms, and handle execution risks. This requires expertise in financial order execution, latency-sensitive websocket pipelines, and Web3 transaction management.
