Who pays when an AI agent buys wrong?
Black Box records what a shopping agent saw and ties it to the PayPal payment. If the buyer disputes, it works out who is at fault, the shop, the agent's operator or the buyer, and tells PayPal what to do.
Every recording below is a real run. The ones marked PayPal went through a sandbox dispute. Dispute scenarios · Live demo · Source
