  "instructions": "Professor Sausages' on-chain counter — everything an agent should check before it signs a transaction: what gas costs, whether the token is a trap, what the swap prices at, and who the address really is. Free tools: find_data, pricing, request_data. Paid tools charge per call in USDC on Base via x402: call one without x_payment to get its exact terms, sign them, and call again with x_payment. No signup, no API keys. Gas covers Ethereum, Base, Arbitrum, Optimism, Polygon and BSC; prices are read from Chainlink oracles on-chain; token safety and swap quotes cover Base and Ethereum. Safety verdicts always ship the evidence that produced them — read it before acting.",
