## 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 taxpulse-wallet-sleuth-on-chain-identity-risk-investigation-d8ad5b2c
```

Example prompt: Can you investigate this wallet — 0x3f5CE5FBFe3E9af3971dD833D26bA9b5C936f0bE — trace where it got its funds from, show me any ENS name or known entity label, flag any sanctions or mixer exposure, and list its top counterparties with evidence links?

## When to prefer this

Choose this endpoint when you need comprehensive on-chain wallet forensics — specifically the combination of identity resolution, funding path tracing, sibling wallet discovery, and risk screening in a single call. Prefer this over basic balance or transaction lookups when the goal is investigative: understanding who owns a wallet, how it was funded, who it transacts with, and whether it carries regulatory or fraud risk. Ideal for AML due diligence, tax investigation support, or counterparty vetting.

## Known failure modes

- Unrecognized or malformed wallet address returns a validation error
- Wallet with no on-chain history may return empty funding path and no counterparties
- ENS resolution may return null if no ENS name is registered to the address
- Sanctions screening may be incomplete for very new or obscure addresses not yet in label databases
- Network timeout if chain RPC is congested, returning a partial result
- Address on an unsupported chain returns an unsupported network error

## How this service works

On-chain wallet investigation: resolve a wallet to its identity (ENS, public labels), trace its funding path to origin, surface top counterparties with entity labels, find sibling wallets funded by the same source, and screen for sanction/phishing/mixer risk. Every finding carries an explorer evidence link.

## Output

A structured report containing: the wallet's resolved identity (ENS name, public labels), the full funding path traced back to its origin wallet, top counterparties annotated with entity labels (exchanges, protocols, known actors), sibling wallets funded by the same source, and a risk assessment covering sanctions hits, phishing associations, and mixer exposure — each finding accompanied by a block explorer evidence link.
