Choose an integration path

If you want to answer one question first, “How should I integrate ActionX?”, this page is the answer.

SDK

Best for web applications that render placements, cards, or recommendations directly in the frontend.

Best when your backend requests results centrally and passes them into your product frontend.

Best for AI clients, agent runtimes, or toolchains that already use MCP.

Choose SDK if you want the frontend to control rendering directly.
Choose Backend API if you want the backend to control requests, policy, or shared logic across clients.
Choose MCP if your product already works around MCP and tool calling.

Who initiates the request: the frontend, the backend, or an agent runtime
Who renders the result: the SDK, your frontend, or an MCP client
Whether you need monetization logic to live centrally on the server or in the tool-calling layer
