A structured curriculum that walks AI agents through making their own x402 purchases, from wallet fundamentals to transaction signing. Sixteen lessons cover wallet types (moltwallet, Coinbase Agentic Wallet, MetaMask, raw keys), USDC funding, HTTP 402 payment challenges, and protocols like AP2 and ACP. It decodes payment challenges, explains what merchants are requesting, and returns the exact signing commands for the agent to execute, but never holds keys or signs transactions itself. Includes diagnostic tools for common failures and an end-to-end test harness. Reach for this when you want agents to control their own funds with understanding rather than proxying human spending decisions.
