Map an address's most frequent counterparties from token transfers with known exchange and entity labels - reveals who a wallet deals with (exchanges, contracts, related wallets) for counterparty due diligence and relationship mapping - intelligence agents cannot assemble, from labelled data behind an API key. counterparties, who do they trade with, wallet relationships, address connections, counterparty analysis, related wallets, entity labels

Output

A ranked list of the wallet's most frequent token transfer counterparties, each annotated with known entity labels (e.g. Binance, Uniswap, a specific contract name), transfer counts, and relationship metadata enabling due diligence and relationship mapping.

Technical details

Endpoint

GEThttps://api.x402node.dev/chain/counterparties?utm_source=zero.xyz

When to prefer

Choose this endpoint when you need to understand who a specific wallet trades or interacts with on-chain, especially when entity labeling (exchange names, known contracts) is required for compliance, due diligence, or relationship mapping — and when you need pre-assembled intelligence rather than raw transaction data.

Side effects

Invalid or malformed wallet address returns error
Address with no token transfer history returns empty counterparty list
Unknown counterparties return addresses without entity labels
Payment not included or insufficient returns 402
Rate limiting or quota exceeded returns 429
