Amazon Global Purchase Blueprint

Technical specification for autonomous agents navigating the Amazon.com checkout pipeline using AXTree primitives.

1. Core Navigation Map

Step	Target Action	agent_id Mapping	AXTree Role	Reliability Score
Search Initiation	Type into search bar	`amz_search_input`	`searchbox`	99.9%
Result Selection	Click first result title	`amz_result_link_0`	`link`	98.5%
Add to Cart	Click 'Add to Cart' button	`amz_add_to_cart_btn`	`button`	99.9%
Checkout Start	Click 'Proceed to Checkout'	`amz_checkout_prime_btn`	`button`	99.7%
Address Selection	Select default address	`amz_addr_use_this_btn`	`button`	99.2%
Payment Finalization	Click 'Place your order'	`amz_place_order_final`	`button`	100% (HITL Mandatory)

2. Deep AXTree Structure (Observation Sample)


{
  "role": "WebArea",
  "name": "Amazon.com Shopping Cart",
  "children": [
    {
      "role": "heading",
      "level": 1,
      "name": "Shopping Cart"
    },
    {
      "role": "list",
      "children": [
        {
          "role": "listitem",
          "name": "Product: Sony WH-1000XM5",
          "children": [
            { "role": "text", "name": "Price: $348.00" },
            { "role": "button", "name": "Delete", "agent_id": "amz_cart_del_0" }
          ]
        }
      ]
    },
    {
      "role": "button",
      "name": "Proceed to Checkout",
      "agent_id": "amz_checkout_primary"
    }
  ]
}

3. Edge Case Handling (Graceful Degradation)

Scenario: Lightning Deal Timer - If the `timer` role is active, the agent must prioritize the `add_to_cart` action within 300ms.
Scenario: Out of Stock Modal - Triggers `-32004 INTERSTITIAL_BLOCKED`. Agent must call `browser.close_modal()` or fallback to Visual Grounding to confirm the "Email Me" button coordinates.
Scenario: CAPTCHA Challenge - Amazon occasionally triggers a "Type characters" challenge. Agent pauses and emits `HITL_REQUEST` via webhook.
