Access prediction markets data from Polymarket
Polymarket is a decentralized prediction markets platform where users can trade on the outcome of future events using blockchain technology. Polymarket provides a comprehensive API, enabling developers and agents to access live market data, event listings, price information, and orderbook statistics to power data-driven workflows and AI automations.
With Polymarket’s API and Sim integration, you can enable agents to programmatically retrieve prediction market information, explore open markets and associated events, analyze historical price data, and access orderbooks and market midpoints. This creates new possibilities for research, automated analysis, and developing intelligent agents that react to real-time event probabilities derived from market prices.
Key features of the Polymarket integration include:
- Market Listing & Filtering: List all current or historical prediction markets, filter by tag, sort, and paginate through results.
- Market Detail: Retrieve details for a single market by market ID or slug, including its outcomes and status.
- Event Listings: Access lists of Polymarket events and detailed event information.
- Orderbook & Price Data: Analyze the orderbook, get the latest market prices, view the midpoint, or obtain historical price information for any market.
- Automation Ready: Build agents or tools that react programmatically to market developments, changing odds, or specific event outcomes.
By using these documented API endpoints, you can seamlessly integrate Polymarket’s rich on-chain prediction market data into your own AI workflows, dashboards, research tools, and trading automations.
