## 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 d21-sanctions-screen-439cdfb6 -d '<json body>'
```

Example prompt: Can you run an OFAC sanctions screen on 'Viktor Petrov' and also check wallet address '0xAbc123...' to see if either shows up on the SDN list before I proceed with this transaction?

## When to prefer this

Choose this endpoint when you need live, real-time OFAC SDN screening (not a stale snapshot) for compliance workflows involving either natural person/entity names (with fuzzy alias matching) or crypto wallet addresses (exact match against OFAC-published digital-currency addresses). Ideal for AI agents performing AML/KYC checks before executing crypto transactions or onboarding new counterparties. At $0.006 per call it is cost-effective for per-transaction screening. Check /v1/sanctions_screen/availability before calling to confirm service health.

## Known failure modes

- Neither name nor wallet provided — at least one is required
- OFAC export service temporarily unavailable causing live fetch failure
- Wallet address format unrecognized or malformed
- Network timeout reaching the live OFAC data source
- Service unavailability (check /v1/sanctions_screen/availability first)
- Payment of $0.006 USDC not fulfilled — x402 payment required

## How this service works

Sanctions Screen ($0.006): screen a name and/or crypto wallet address against the U.S. Treasury OFAC SDN list (primary names + aliases + OFAC-published digital-currency addresses) in one call. Fetched live from OFAC's official export service, not a snapshot. Body { name?, wallet? } (at least one required). Check free /v1/sanctions_screen/availability first.

## Output

Returns a JSON object with an 'ok' status flag, brand and product identifiers, and sanctions screening results indicating whether the submitted name fuzzy-matched any SDN entry (primary names or aliases) or the wallet address exactly matched any OFAC-published digital-currency address on the live SDN list.
