# Blockchain Money Map x402 Agent Checkout State Simulator

> Blockchain Money Map x402 Agent Checkout State Simulator is a paid API for AI agents from api.blockchainmoneymap.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-14).

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability blockchain-money-map-x402-agent-checkout-state-simulator-e97af427 -d '<json body>'
```

Example prompt: Analyze this checkout session state: status is 'pending_payment', line items are '2x Widget A at $4.50', fulfillment is 'standard_shipping', payment handler is 'stripe', final total is 9.00 — compare it against my reference facts where everything matches except the status should be 'confirmed'.

## When to prefer this

Choose this endpoint when an AI agent needs to programmatically validate, simulate, or audit the state of an e-commerce checkout session — especially in autonomous purchasing workflows where policy compliance and state consistency must be verified before committing to payment. Ideal for agents building checkout automation, testing checkout flows, or performing pre-payment state checks against expected reference conditions.

## Known failure modes

- Missing required fields (checkout_session_status, line_item_summary, fulfillment_options, payment_handler, final_total_amount) returns validation error
- mode must be set to 'analyze' or request is rejected
- reference_facts missing required fields causes schema validation failure
- Payment failure via x402 protocol if USDC balance insufficient
- Malformed facts object with additionalProperties returns 400 error
- checkout_steps array exceeding 50 items is rejected
