Resolved Markets vs Polymarket API
Polymarket native APIs are the official source for current market state and exchange interaction. Resolved Markets is the historical archive and research layer: full-depth snapshots, timestamped replay, ClickHouse-backed analytics, OpenAPI, MCP, WebSocket, and CLI export. Use the right tool for the job; many teams use both.

Frequently asked questions
Is Resolved Markets a replacement for the Polymarket API?
No. Resolved Markets complements Polymarket. Use Polymarket native APIs for official live exchange interaction; use Resolved Markets when you need historical orderbook snapshots, full-depth replay, cross-category research data, WebSocket streaming, OpenAPI, or MCP tooling.
Does Polymarket provide historical orderbook depth?
Polymarket provides live CLOB data and market metadata, but it does not publish a queryable historical archive of full orderbook depth. Resolved Markets stores that archive in ClickHouse and exposes it through API endpoints.
Can I trade through Resolved Markets?
No. Resolved Markets is a read-only data and research platform. It does not place trades, custody funds, or route orders. Trading still happens through Polymarket or other venues directly.
Which API should AI agents use?
For research, analytics, and historical questions, AI agents should use Resolved Markets through MCP, OpenAPI, or REST. For order placement or official exchange actions, agents need the relevant venue API directly.
