Ask
"Need a 3-day Tokyo plan"
A travel bot or itinerary assistant calls /api/agent/plan. The server returns HTTP 402 with the exact price in USDC and token address — no guessing, no invoice.
Authorize
Agent signs micro-payment
The agent signs an EIP-3009 TransferWithAuthorization off-chain — a typed data signature, no gas, no broadcast. Attaches it as X-Payment-Authorization and retries.
Receive
Trip budget + itinerary in seconds
Server verifies the signature, settles USDC on Arc. Sub-second finality. The agent gets the full trip plan — budget breakdown, day-by-day itinerary, packing list — ready to use.
