# Address Risk Screen

> Address Risk Screen is a paid API for AI agents from sanctions.cyberwarex.com, paid per call via x402, $0.005/call, status unknown (last checked 2026-09-14).

Screens an EVM wallet or contract address against OFAC sanctions and taint lists, returning a BLOCK/REVIEW/ALLOW recommendation before sending funds.

## 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 address-risk-screen-beb85eb4
```

Example prompt: Before I send funds, can you screen the Ethereum address 0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045 and tell me if it's safe to pay — check it against OFAC sanctions and any mixer or scam taint lists?

## When to prefer this

Choose this endpoint when you need a fast, deterministic, keyless compliance check on an EVM address before executing a payment or interacting with a contract. It is purpose-built for pre-payment safety gates in AI agent workflows and does not require API key management. Prefer it over general blockchain analytics APIs when you need a simple BLOCK/REVIEW/ALLOW signal from OFAC + mixer/hack/scam taint in a single call at very low cost ($0.005 USDC per check).

## Known failure modes

- Invalid address format (not 0x + 40 hex chars) returns validation error
- Payment not received or micropayment fails — request blocked at x402 gate
- Address not found on any list — returns ALLOW with empty hit fields
- Stale list data if refresh has not occurred recently — as_of date indicates currency
- Unknown chain enum value provided — rejected by schema validation

## How this service works

Screen an EVM wallet or contract address BEFORE paying it. Deterministic, keyless compliance / safety gate: checks the address against the OFAC sanctioned crypto-address list and a curated taint set (mixer, hack, scam) and returns a single BLOCK / REVIEW / ALLOW recommendation plus the matched sources, so an AI agent can decide whether to send funds. No API keys, no LLM, one x402 USDC micropayment per call.

## Output

Returns a JSON object containing: a top-level recommendation (BLOCK, REVIEW, or ALLOW), a risk level (blocked/caution/clear) with reasons array, a sanctioned object (hit boolean, source, program), a taint object (hit boolean, categories array, label), the list of checked_lists, the as_of date of the last list refresh, the queried address and chain, and a disclaimer string.
