Poll transaction status. When the SLA deadline passes and the transaction is still escrowed, it is automatically released.

Statuses: pending → escrowed → fulfilled → released (or disputed / refunded).

Seller confirms delivery. Transitions transaction from escrowed to fulfilled, triggering escrow release.

Buyer submits shipping address for a physical goods order. Only accepted when product.category === "physical".

  "recipientName": "Acme Corp Robot",
  "addressLine1": "123 Automation Blvd",
  "city": "San Francisco", "state": "CA",
  "postalCode": "94105", "country": "US"
}

Get shipping status, tracking number, and delivery timestamps.

Seller updates tracking number, carrier, estimated delivery, and/or status. When status is set to "delivered", the transaction is automatically fulfilled.

  "trackingNumber": "1Z999AA10123456784",
  "carrier": "UPS",
  "shippingStatus": "shipped"
}

  "budgetLimit": 100.00,
  "ownerId": "uuid-of-owner"
}
