  "instructions": "On-chain facts for the seconds before you transact: live gas across Ethereum, Base, Arbitrum, Optimism and Polygon; an ERC-20's decimals and symbol read from the contract; whether a transaction actually succeeded; and an address's balance and next nonce. Tool calls are x402-paid in USDC on Base — send the base64 X-PAYMENT header on this POST /mcp request (or params._meta['x402/payment']). gas_now, token_info and tx_status cost $0.005; address_info $0.008. An unpaid call returns a PaymentRequired result and settles nothing; initialize, ping and tools/list are free, as are request_data and demand_report. An unknown transaction or an address with no contract code is reported honestly and is NOT charged. These values are perishable: call again rather than caching.",
