Resolved Markets provides historical and live Polymarket order book data through REST, WebSocket, and MCP access for backtesting and research.

What is Resolved Markets?
Resolved Markets is a data platform that captures order book snapshots and trades from Polymarket prediction markets and Hyperliquid perpetual futures. Each snapshot includes full bid and ask depth, mid prices, spreads, and crypto spot prices, and the data can be replayed by timestamp to study how markets moved. Access is through a REST API, WebSocket streams on paid plans, historical exports, and an MCP server for AI agents. A free tier covers crypto markets with full history, and paid plans can be bought by card, with crypto, or per request over x402 in USDC. An open-source backtesting kit, resolvedkit, is published under the MIT license.
