What is AP2?

Problem: AI agents spending money. Who approved it?

AP2 = Payments with Mandates — cryptographically signed proof of user intent.

MANDATE = { userId, maxAmount, expires, signature }

Flow (matches real-world AP2):

User asks for cheeseburger 🍔
Your agent searches restaurants via A2A (discovers DoorDash/UberEats/Grubhub agents)
Your agent gets menus and delivery estimates
Your agent decides which restaurant (cheapest/fastest)
User authorizes payment → User's authorization service creates mandate (signed with user's private key)
Your agent requests authorization → Receives mandate from user
Your agent sends payment request WITH mandate to Stripe agent (via A2A)
Stripe agent VERIFIES mandate (signature valid? not expired? amount ok?)
If valid → Stripe processes payment ✅
Your agent places order with food delivery agent (DoorDash/UberEats/Grubhub via A2A)
🍔 Burger incoming!

Key Point: The agent NEVER creates mandates. User authorization creates them. Agent only uses them.
