AP2 Flow Simulator
Step through an Agent Payments Protocol purchase as an animated sequence diagram — human-present (CartMandate) and human-not-present (IntentMandate) — from shopping prompt through mandate signing to authorization with agent-presence signals.
A user delegates shopping to an AI agent but approves the final cart themselves. The merchant signs the exact cart (CartMandate), the user counter-signs it on a trusted surface, and a PaymentMandate carries agent-presence signals to the network/issuer alongside normal authorization.
Shopping Prompt
User delegates the task to the agent in natural language.
"Buy me white running shoes, size 10, under $150." The agent may confirm its understanding back to the user — this playback becomes part of the auditable trail.
