## 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 crypto-address-risk-screening-1dcbf1d7
```

Example prompt: Before I send funds, can you screen the Ethereum wallet 0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045 for sanctions or any risk flags?

## When to prefer this

Use this endpoint when you need a fast, per-call blockchain address risk/AML screening across major EVM chains (Ethereum, Base, BSC, Polygon, Arbitrum, Optimism, Avalanche) without signing up for an API key. Prefer over full KYC platforms when you only need address-level verdicts, not entity-level compliance reports. Ideal for AI agents performing pre-payment due diligence or DeFi transaction screening.

## Known failure modes

- Missing or invalid address format returns a 400/validation error
- Unsupported chain identifier returns an error
- Address with no on-chain history may return CLEAR with zero risk but no guarantee of safety
- Payment failure via x402 (insufficient USDC balance) returns 402 Payment Required
- Rate limits or upstream data provider outage may return 503

## How this service works

Machine-payable data APIs for AI agents across web search, on-chain reads, trading data, market judgment, and AI visibility. The canonical x402 catalog currently exposes 85 paid routes. Pay per call in USDC via x402 on Base. No API keys, no signup.

## Output

Returns a JSON object with the wallet address, chain, a CLEAR/FLAGGED verdict string, boolean sanctioned status, integer risk_count, and an array of specific risk flags (e.g. hacker, scammer, mixer) detected for that address.
