> Understand how ActionX is layered across access, decisioning, observability, and settlement.

This page explains ActionX through its capability layers instead of exposing internal service names.

## The four capability layers

<Columns cols={2}>
  <Card title="Access layer">
    Exposes SDK, Backend API, and MCP entry points for different product architectures and request paths.
  </Card>

  <Card title="Decision layer">
    Understands intent, retrieves candidates, evaluates relevance, and determines the final result to return.
  </Card>

  <Card title="Supply layer">
    Aggregates product, program, and partner resources to keep the platform supplied with matchable candidates.
  </Card>

  <Card title="Observability and settlement layer">
    Handles event capture, performance analysis, and revenue flow to complete the operational loop.
  </Card>
</Columns>

## How each role sees the platform

* Publishers care most about Dashboard, Analytics, Billing, and Withdrawals.
* Developers care most about integration paths, request structure, and returned results.
* Advertisers and partners care most about supply, traffic context, and performance validation.
