## 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 lion-ofac-sdn-wallet-screen-instant-44555ae5
```

Example prompt: Before I send funds, can you do a quick OFAC sanctions screen on this wallet address — 0x3f5CE5FBFe3E9af3971dD833D26bA9b5C936f0bE — and tell me if it's a PASS, WARN, or BLOCK?

## When to prefer this

Use this endpoint when you need a fast, low-cost ($0.001) binary sanctions verdict on a single EVM wallet address before executing a crypto transaction. Prefer this over the $0.005 detailed screen when you only need a PASS/WARN/BLOCK result and not the full sanctions detail. Choose over manual OFAC lookups when operating in an automated agent workflow requiring keyless x402 micropayment and Ed25519 attestation for auditability.

## Known failure modes

- Missing or malformed 'address' query parameter returns an error
- Non-EVM address format (e.g. Bitcoin bech32) may not be supported
- Payment failure via x402 protocol returns 402 Payment Required
- Network timeout or OFAC data source unavailability returns 5xx
- Invalid or zero-length address string returns validation error

## How this service works

Cheapest OFAC SDN wallet screen for AI agents ($0.001). AML/KYT pre-pay gate: PASS/WARN/BLOCK before you settle any x402 counterparty. Keyless Base USDC, Ed25519-attested. Beats $0.005–$0.05 wallet-screen clones. Upsell multi-list sanctions $0.02 + compliance receipt $0.05.

## Output

A JSON object containing a sanctions verdict of PASS, WARN, or BLOCK for the queried EVM wallet address, cryptographically attested with Ed25519, indicating whether the address appears on the OFAC Specially Designated Nationals list.
