Polymarket API guide
Polymarket offers public APIs for market data and a separate order API for trading. Here is how the pieces fit for a data project.
- Use the market-data endpoints to list markets and fetch prices.
- Use the order book endpoints for depth.
- Store your own history if you need it, or use a historical data provider.
- Respect rate limits and terms of use.
