Your AI agent pays by the request, in fractions of a cent.
Tell the agent what to shop for. It queries dozens of merchant APIs, pays each one $0.001 – $0.0025 per call over x402, and hands you the best deal. Settlement is batched on Arc L1 in USDC — gas costs that would kill this model on Ethereum become a rounding error here.
