Polymarket SDKs and developer libraries
A client library helps your code work with a documented interface. Select it for the data, account operation or research task you need, rather than assuming every Polymarket SDK covers the same services.
How to choose sdks & libraries
Map library coverage to your application
Check the methods you intend to call and the API behind each one. A library for one service or action may not cover market discovery, historical data and trading together. Compare language support with your application’s runtime and deployment requirements.
Review before adopting
- Confirm the programming language and supported deployment environment.
- Check the exact API methods and data or account operations the library documents.
- Identify any hosted service, API entitlement or credential required in addition to installing the package.
Downloading a library supplies code, not automatic access to a hosted dataset or permission to trade. Keep API access and signing permissions separate from package installation. Choose a CLI for command-line work or an MCP server when the intended caller is an assistant.
