What agents use it for

Procurement

Agent notices server load is high. Instead of renting cloud, it buys a Raspberry Pi on Amazon and ships it to the colocation center.

Gifting

Agent detects its owner's birthday. Searches for "cool mechanical keyboard." Buys it. Ships it. Surprise.

Supply chain

Agent monitors inventory levels of 3D printer filament. Auto-orders refills when low. Manufacturing on autopilot.

Arbitrage

Agent spots a price difference between eBay and StockX. Buys low. Lists high. Automated physical arbitrage.
