Get Address Counterparties Data

post

Get top counterparties that wallet addresses have interacted with, supporting different grouping options (wallet or entity) and source filtering (Combined, Tokens, ETH). Returns interaction statistics including volume, frequency, and timing data.

What it helps to answer:

• Most frequent transaction partners by count and volume

• Net value flows between addresses (inflows vs outflows)

• Exchange and protocol interaction patterns

• DeFi protocol usage and DEX trading counterparties

• High-value transfer relationships and funding sources
