- The author walks through a 12-step demo of what "agentic commerce" looks like: an agent gets a wallet with $10 USDC from its human and a task — "I'll fly to Berlin tomorrow, do I need to pack warm clothes?"
- The agent pays $0.001 to search for weather API endpoints on x402 Trust, picks one, finds 3 warning flags (v1 envelope, body-only, shared payTo wallet), spends another $0.005 on a paid score breakdown, confirms its MCP can speak v1, then buys the 7-day Berlin forecast for $0.054 USDC — verdict: windy with 70% chance of rain.
- No account, sign-up, or identification involved anywhere. Total cost: 6 cents; total time: 10 seconds. The author argues it's no longer "if" but "when" this becomes part of daily life.
