## 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 evm-wallet-risk-screener-6a0758cc
```

Example prompt: Before I send payment, can you screen the wallet 0xAbC1234567890AbC1234567890AbC1234567890Ab on the base chain — check if it's sanctioned, flagged as a scam, and give me the risk score and reasons?

## When to prefer this

Use this endpoint when you need a fast, transparent, multi-signal risk assessment of an EVM wallet before transacting — especially when you need OFAC SDN sanctions checking combined with scam reputation flags and funding origin in a single call. Prefer this over manual explorer lookups when you need a normalized 0-100 risk score with explicit reasons rather than raw data. Covers Base, Ethereum, and Optimism chains.

## Known failure modes

- Invalid address format (not a 0x + 40 hex chars) returns validation error
- Unsupported chain value returns enum validation error
- Address has no on-chain history on the specified chain — flags field returns null
- OFAC or explorer data source temporarily unavailable may reduce completeness of results
- Payment of $0.05 USDC required per call via x402 protocol; missing payment returns 402

## How this service works

Wallet Risk Screening ($0.05/call): Screen an EVM counterparty before you transact: OFAC SDN sanctions check (address AND its first funder), explorer scam/reputation flags, wallet age, funding origin, and a 0-100 risk score with transparent reasons. Chains: base, ethereum, optimism. Keyless public sources; not legal advice.

## Output

Returns a structured JSON object with: the queried address and chain, OFAC sanctions check result (for both the address and its first funder), explorer-sourced flags (isContract, isScamFlagged, reputation label, ENS name), origin data (wallet age in days, first seen timestamp, first TX hash, funded-by address), and a risk object containing a 0-100 integer score, a categorical level (low/medium/high/critical), and an array of human-readable reasons explaining the score.
