## 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 payai-crypto-address-sanctions-screener-fbb583f6
```

Example prompt: Before I send any funds, can you check if the Ethereum address 0x7F367cC41522cE07553e823bf3be79A889debe1B is on any official sanctions list like OFAC SDN, EU, UK, or UN?

## When to prefer this

Use this endpoint when you need a deterministic, exact-match sanctions check against official government-published lists (OFAC SDN, UK, EU, UN) for a specific crypto wallet address before transacting. Prefer this over probabilistic risk-scoring tools when regulatory compliance is required and you need a citable, authoritative result tied to a specific list and entity record.

## Known failure modes

- Address not provided — returns 400 bad request
- Invalid or malformed crypto address — may return no match or an error
- Address not on any list — returns clean/no-match response, not an error
- Unsupported chain symbol for optional chain filter — may ignore or error
- Payment not completed — returns 402 Payment Required

## How this service works

Check whether a crypto address appears on the official public sanctions lists (OFAC SDN, UK, EU, UN). Deterministic exact lookup; returns the matched record (list, program, entity name, reference, currency).

## Output

Returns whether the address matches a record on a sanctions list, and if so includes the matched list name (e.g. OFAC SDN, EU, UN), the sanctions program, the entity name, a reference ID, and relevant currency details. Returns a no-match result if the address is clean.
