## 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 strale-web3-counterparty-due-diligence-bd6dbcdb -d '<json body>'
```

Example prompt: Run a Web3 counterparty due diligence check on wallet 0x742d35Cc6634C0532925a3b844Bc454e4438f44e on Ethereum — the entity is possibly 'Tornado Cash' and I need to know if it's sanctioned or flagged as a PEP before we proceed with a payment.

## When to prefer this

Use this endpoint when you need structured compliance due diligence on a blockchain wallet address before transacting — especially for AML screening, sanctions checks, or PEP verification in a Web3 context. Prefer over generic blockchain explorers when you need a compliance-grade audit trail with structured JSON output.

## Known failure modes

- Invalid or malformed wallet address returns validation error
- Unsupported chain_id returns error indicating chain not available
- Wallet with no on-chain history may return minimal data
- Network timeout on chain data lookup
- Rate limiting if too many requests in short window

## How this service works

Full compliance check on a wallet address before transacting. Combines on-chain risk scoring with off-chain entity compliance — wallet risk, wallet age, ENS identity resolution, sanctions screening, PEP check, and adverse media scan.

## Output

Returns a structured JSON compliance report with sanctions screening results, PEP status, on-chain financial activity summary, risk scoring, and a full audit trail suitable for compliance documentation.
