TraceFast knowledge graph: top counterparties of an Ethereum address, current or as of a block. Up to 100 addresses it interacts with most, ranked by successful transactions across top-level calls, internal calls and token transfers, each with transaction counts and first/last block. Path address: 0x-prefixed, 40 hex. Query block: integer, state at the end of this block, absent = current; limit: integer 1..100, default 100.
