TraceFast live Ethereum data: balanceOf(address) for one token at the end of a block, read

TraceFast live Ethereum data: balanceOf(address) for one token at the end of a block, read from contract storage. A token outside the covered set is refused (422), never a fake zero. Path address and token: 0x-prefixed, 40 hex. Query block: integer, state at the end of this block, absent = current. Docs: https://docs.tracefast.xyz/api/address-token-balance.md
