3. After payment, booking is confirmed automatically

**If the agent has wallet capabilities (e.g., evm-wallet skill):**
```bash
# Check USDC balance on Base
node src/balance.js base --json

# Send USDC to deposit address
node src/send.js base USDC <deposit_address> <amount_usdc> --yes --json
```

2. Present options
3. User picks one → collect passenger details
4. POST /v1/book with passenger info
5. Share payment URL → user pays in USDC
6. Confirm booking → share confirmation page

### Multi-passenger
User: "We need flights for 3 people, Seoul to Bali, April 1-10"
1. Search with adults=3
2. Prices shown are per-person
3. When booking, collect details for all 3 passengers
4. Total USDC amount = per-person × 3
