## 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 walletrep-evm-wallet-risk-reputation-scorer-e16b298f -d '<json body>'
```

Example prompt: Can you run a risk and reputation check on this Ethereum wallet — 0x742d35Cc6634C0532925a3b844Bc454e4438f44f — and tell me if it's clean, suspicious, or blacklisted, along with its 0-100 score?

## When to prefer this

Use this endpoint when you need multi-source wallet risk scoring that combines sanctions screening (Chainalysis, TRM, OFAC) with GoPlus security flags and on-chain signals into a single normalized score and tier. Prefer it over single-source blacklist checks when you need comprehensive KYT/AML due diligence before transacting with an unknown counterparty on Base or Ethereum mainnet.

## Known failure modes

- Invalid or malformed wallet address returns a validation error
- Unsupported chain value (not 'base' or 'ethereum') returns an enum error
- Payment of 0.01 USDC on Base not provided — 402 Payment Required
- Downstream oracle (Chainalysis, TRM, GoPlus) timeout may result in partial scoring or service unavailable
- Address with no on-chain history may return limited scoring confidence

## How this service works

Score the risk and reputation of any EVM wallet address before you transact with it. Combines on-chain sanctions screening (Chainalysis oracle, TRM, OFAC) and GoPlus address-security flags (phishing, blacklist, mixer, malicious activity) with contract-vs-EOA detection, transaction history and balance into a 0-100 score and clean/suspicious/blacklisted tier. Use it for wallet screening, counterparty due diligence and KYT. Ed25519-signed. 0.01 USDC on Base.

## Output

Returns a 0-100 risk score and a tier classification (clean, suspicious, or blacklisted) for the given wallet, along with detailed flags from Chainalysis, TRM, OFAC, and GoPlus: sanctions status, phishing association, mixer usage, malicious activity, blacklist presence, whether the address is a contract or EOA, transaction history summary, and current balance. Response is Ed25519-signed.
