Polymarket runs on a public blockchain and exposes a comprehensive REST API. Every market, position, trade, and order is accessible — which means builders and quantitative analysts can pull the full history of prediction market activity and run whatever analysis they want. The tools in this section help developers and data scientists access, process, and work with that data efficiently.
Wrapper libraries handle authentication, pagination, and rate limiting so you can focus on the analysis rather than the plumbing. Some tools go further and provide pre-built datasets: historical probability timeseries for every resolved market, aggregated holder statistics, and cross-market correlation matrices ready to load into a Python notebook or SQL database.
If you are building on Polymarket — whether that is a trading bot, an analytics dashboard, or a research tool — starting with a solid data layer is the difference between shipping fast and spending weeks debugging API quirks. The tools listed here cover the full stack from raw API access to structured datasets and SDKs.
