TraceFast live Ethereum data: one address as the chain sees it now — how it exists (an account whose state was touched, or an address only ever mentioned by other operations), whether it holds code, its native balance and nonce, when it was first mentioned and last active in any form, and its direct-transaction counters. Path address: The address, `0x`-prefixed, 40 hex characters, any case. Docs: https://docs.tracefast.xyz/api/address.md
