  "description": "TraceFast live Ethereum data: three different questions about when an address was active, each answered separately — when it was first mentioned anywhere on chain; when its own account state last changed and how many times it changed; and the newest block at which it took part in anything (a top-level transaction, a token transfer, an emitted log, a value-bearing call), with the sources that answer was… Path: address.
