list_productsList everything the demo store sells, with product ids and prices. Prices are in USD.
create_checkoutStart a checkout (an Agentic Commerce Protocol checkout session) with the products and quantities the user wants. Returns the session id, the cart and its total. If no api_key is given, a sandbox key is created and returned.
update_checkoutReplace the items in an open checkout (e.g. the user changed their mind). Any PayPal payment created for the old total is dropped.
get_checkoutRead the current cart, total, payment status and order of a checkout.
request_paypal_paymentCreate a PayPal (sandbox) payment for the checkout's exact total. Returns approve_url, the PayPal link where the user approves the payment.
wait_for_payment_approvalWait (up to 45s per call) until PayPal reports the user approved the payment. Returns still_waiting if the user has not approved yet.
complete_checkoutPlace the order. With payment "paypal" the approved PayPal payment is captured first, and the order only goes through if PayPal confirms the money for the exact total. "mock" skips real payment (testing only).
