# Polymarket SDKs and developer libraries | Page 2

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.
