## 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 chainverdict-ofac-sdn-address-screener-958e63f5
```

Example prompt: Can you screen the Ethereum address 0x1234567890abcdef1234567890abcdef12345678 against the OFAC SDN list to see if it's sanctioned before I send funds?

## When to prefer this

Use ChainVerdict when you need a pay-per-call, low-cost OFAC SDN screening specifically for EVM blockchain addresses, especially in agent workflows that require micropayment-gated compliance checks via the x402 protocol. Prefer this over bulk compliance services when you only need on-demand, single-address lookups at $0.001 per call with no subscription overhead.

## Known failure modes

- HTTP 402 returned if payment is not provided via x402 protocol before calling
- Invalid or malformed EVM address may result in a 400 error or no match
- Address not found in SDN list returns a clean/not-sanctioned result (true negative)
- Network timeouts or upstream SDN list unavailability may cause 503 errors
- OFAC list may have propagation delay meaning very recently added addresses could be missed

## How this service works

x402 v2 pay-per-call. Unpaid requests receive HTTP 402 with payment requirements.

## Output

Returns a compliance verdict indicating whether the given EVM address appears on the OFAC Specially Designated Nationals (SDN) list, including match status and any relevant sanctions details about the address.
