Returns a grade (BASED/MID/COOKED/RADIOACTIVE) based on the contract's own state
Returns a grade (BASED/MID/COOKED/RADIOACTIVE) based on the contract's own state: code size, name, symbol, decimals, supply, owner(), proxy slots. Returns: grade (BASED/MID/COOKED/RADIOACTIVE, a stated rule over the contract's own state), a one-liner and a roast, and the facts read: code size, name, symbol, decimals, supply, owner(), proxy slots. It does not read holders, liquidity or price and makes no safety or legitimacy call. Query: token (token contract, 0x + 40 hex).
Paid test badge: not yet. The checks above are free: we call the tool without paying and read the payment request it sends back. The Verified badge needs paid calls whose answers match the promised output, and nobody can buy a badge.
