A recommendation you can check
Ask for a wireless ergonomic keyboard under $150. Claude compares our three-product demo catalog. The server checks the item, price and budget.
AI SHOPPING HELP + PAYPAL SANDBOX
Find the right purchase.
Stop the wrong payment.
For buyers who want AI to find a useful product without giving an agent unrestricted permission to spend.
An order with the exact terms
Review the 119.00 USD choice, then create a real PayPal sandbox order. AgentPay checks the amount, currency and merchant against your saved purchase.
THE MOMENT THAT MATTERS
What if the amount changes?
Try a price ten times higher. The backend refuses the altered terms and records why. Creating an order, retrying it or asking AI never becomes permission to pay.

Judges: no account setup needed
Use the judge email and password from the Devpost testing instructions. You do not need to create an account or use a personal payment account for the proposal, order-check and refusal demo.
Sign in with judge credentialsEvaluation purchases belong only to the sandbox workspace. The account cannot authorize a payment. A saved AI proposal and sandbox order are ready to inspect. Live AI is limited to three requests per account per hour; inspecting saved results does not use that quota.
Running the source yourself?
The standalone package includes its own setup instructions, database migrations, tests and authorization SDK. Follow the README to configure your own sandbox services. Private 2AYE source is not needed for the demonstrated proposal-to-order flow.
What is outside this demonstration?
This demo prepares and verifies an order; it does not complete a purchase. Payment still needs a genuine signed human approval, the buyer approving PayPal checkout, and a verified payment result. Payment execution remains off. No independently verified hardware or completed-payment claim is made.
The changed-price test checks stored order terms. It does not demonstrate tampering with an already signed payment approval.
