channel3

A shopping agent that spends only what you allow. Write a spending mandate in plain words, consent once with PayPal vault, and the agent shops via Channel3. A deterministic policy engine, not the model, decides: pay, ask you, or refuse. Built for the PayPal AI Hackathon 2026.

Trust the deal, not the stranger. AI catches the scam before money moves, PayPal holds the payment until the item really arrives, and AI agents negotiate a fair price. Live on the PayPal sandbox.
