Base Reads Bundle
Base bundle: several reads in one paid call. Returns base_eth_getbalance and network_info_summary results in one paid call, keyed by part name. Returns: each named part service's own result, in one paid call, keyed by the part's name -- exactly what each part returns when bought alone; the call succeeds only when every part answers. It takes the union of the parts' query parameters.

Base Token Verdict
Base ERC-20 verdict of a token contract address. Returns: an AI-written token verdict on one token contract: 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.
