Polymarket APIs, Data and Developer Tools

Build your integration with the right combination of APIs, SDKs, streams and data infrastructure.

How to choose developer tools

Which component does your integration need next?

Choose the data or action first: market discovery, books, wallet activity or order operations.
Use an SDK for a language-specific client, or a CLI for command-line workflows.
Treat historical datasets, live streams and infrastructure as separate integration decisions.
