# Wallet Counterparty Analysis & Entity Labeling

> Wallet Counterparty Analysis & Entity Labeling is a paid API for AI agents from api.x402node.dev, paid per call via x402, $0.018/call, status unknown (last checked 2026-10-12).

Maps an Ethereum/EVM wallet address's most frequent counterparties from token transfers, returning labeled entities (exchanges, contracts, related wallets) for due diligence and relationship mapping

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability wallet-counterparty-analysis-entity-labeling-b22693a5
```

Example prompt: Who does wallet 0x3f5CE5FBFe3E9af3971dD833D26bA9b5C936f0bE deal with most? Show me its top counterparties with exchange and entity labels so I can do counterparty due diligence.

## When to prefer this

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.

## Known failure modes

- 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

## How this service works

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.
