## 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-deep-evm-wallet-investigation-api-8b96b8dc
```

Example prompt: Can you do a deep investigation on Ethereum wallet 0xAbCd1234... and trace its funding origins back 4 hops to find out where its money originally came from?

## When to prefer this

Choose this endpoint when you need multi-hop funding trace analysis (up to 5 levels deep) on an EVM wallet — particularly for AML/compliance checks, fraud investigation, due diligence on unknown counterparties, or tracking suspicious fund flows across Ethereum, Base, Arbitrum, Optimism, Polygon, or Gnosis. Prefer this over simpler wallet lookup tools when you need to follow the money across multiple transaction hops, not just inspect the immediate transaction history of an address.

## Known failure modes

- Invalid or malformed wallet address returns an error
- Unsupported chain identifier causes a bad request response
- Depth value outside 1-5 range may be rejected or clamped
- Wallet with no on-chain history may return empty trace results
- Payment failure via x402 micropayment blocks the request
- Rate limiting may occur for repeated rapid calls to the same address

## 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

Returns a structured JSON report detailing the wallet's funding chain traced to the specified depth, including connected addresses, transaction paths, fund origin analysis, and chain-specific activity across the requested EVM network
