Guided Scenarios
Pre-built demos that run tool calls step by step
Search for sneakers, add to cart, and complete checkout, the simplest E2E flow. If the demo payment options are enabled, complete_checkout charges the chosen method with test funds; with them off, nothing is charged.
Search, cart, and checkout for boots on Demo Store. complete_checkout waits for the buyer's approval, then places a simulated order with payment_method MOCK: COMPLETED with an order_id, and no money moves.
Search products, compare two options by price and rating, then purchase the best match.
8-signal scoring pipeline in action: agent evaluates trust signals, tier assignment, and rule engine before purchasing. If the demo payment options are enabled, complete_checkout charges the chosen method with test funds; with them off, nothing is charged.
UCP identity linking provides a 10% gold-tier loyalty discount. Demonstrates legitimate discount vs. fraud detection. If the demo payment options are enabled, complete_checkout charges the chosen method with test funds; with them off, nothing is charged.
Agent uses UCP but the store lists a different protocol. The router selects the store's protocol with translationRequired=true (AP2 is not available as a checkout protocol today; this walkthrough only illustrates the routing decision and settles nothing over AP2). If the demo payment options are enabled, complete_checkout charges the chosen method with test funds; with them off, nothing is charged.
A bot-like agent (velocity 1500ms) with promo abuse signals (15 probes) is blocked by R003 + R004 before checkout. If the demo payment options are enabled, complete_checkout charges the chosen method with test funds; with them off, nothing is charged.
The store publishes a $500.00 cap per order in its agent policy. The agent puts a $2,499 item through: the preview passes — merchant rules are not evaluated there — and the denial lands at settlement, with CHECKOUT_BLOCKED_BY_POLICY and no order created. The agent then buys within the cap. The limit here belongs to the merchant; the sibling scenario covers the one the agent carries. If the demo payment options are enabled, complete_checkout charges the chosen method with test funds; with them off, nothing is charged.
The agent presents a payment mandate capped at $200 and tries a $260 order. Trusteed denies it with a structured explanation the agent can act on (the mandate's own limit, so nothing about the merchant leaks), and the agent corrects the cart and completes. The limit here is the one the agent brings; the merchant's own cap is a separate axis, covered by the high-value order scenario. If the demo payment options are enabled, complete_checkout charges the chosen method with test funds; with them off, nothing is charged.
The merchant's own price moves between the approved preview and the execution. Trusteed revalidates against the authoritative catalog and asks the agent to reconfirm the exact state before settling. A stock shortfall blocks instead, because reconfirming cannot fix it. If the demo payment options are enabled, complete_checkout charges the chosen method with test funds; with them off, nothing is charged.
