# Polymarket APIs, data and developer tools | Page 3

Start with the data or action your application needs, then choose a compatible interface and access model. This family covers building blocks for research applications, data systems and trading integrations.

How to choose developer tools

## Choose the building block

-   APIs supply documented datasets or actions; SDKs and GitHub libraries help integrate them into code.
-   Historical datasets support retrospective work, while streams provide ongoing updates.
-   MCP servers expose tools to assistants; command-line tools offer a different operating interface.
-   Indexing tools and builder resources support data infrastructure and application development.

## Check compatibility before integrating

Compare programming languages, runtime and deployment requirements, API coverage and entitlements. A repository can supply code without granting access to a hosted dataset. Read the relevant software and data licensing terms.

Separate public research reads from account operations. Establish the credentials and permissions needed for each action before enabling them in your application or agent. Move to infrastructure tools when the main task is running the service rather than choosing its data interface.
