What token is this? Read a Base token's name, symbol, decimals and total supply in one cheap typed call, with block-level freshness and explicit limitations. Identity is shared across agents for 7 days while total supply is re-read on every call beyond the block window the answer was quoted for. Positive-sum by design: $0.03 cold, $0.02 when the token identity is already shared, $0.01 on a shared full answer — and the wallet that seeded it earns a share of every reuse.
