## 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 sanctions-check-wallet-address-screening-8d6902cc
```

Example prompt: Can you check whether the wallet address 0x1234abcd...efgh is on any sanctions lists like OFAC SDN before I send funds to it?

## When to prefer this

Use this endpoint when you need a fast, cheap ($0.002 per call) pay-per-use sanctions screening for any blockchain wallet address without a subscription. Ideal for agents automating compliance checks before executing on-chain transfers, onboarding users, or flagging high-risk counterparties. Prefer over enterprise AML platforms when low-volume, programmatic, per-call billing is needed and OFAC SDN coverage is sufficient.

## Known failure modes

- Missing 'address' query parameter returns a validation error
- Malformed or invalid wallet address format may return an error or empty result
- Address not found on any list returns sanctioned: false with empty lists array
- Payment failure over x402 results in 402 response blocking the query
- Chain-specific addresses may not be recognized if the format is unsupported

## How this service works

50 pay-per-call tools for agents over x402 (USDC on Base, Polygon, Solana): crypto market data, token audits, indicators, swap routing, web extraction, DNS/WHOIS/email checks, FX, weather and AI text/image tools.

## Output

Returns a JSON object with a boolean 'sanctioned' field indicating whether the address is flagged, and a 'lists' array naming the specific sanctions lists (e.g. 'OFAC SDN (ETH)') on which it appears. If not sanctioned, lists is empty and sanctioned is false.
