## 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 factline-wallet-evidence-check-5246cfdb
```

Example prompt: Can you check whether the wallet 0x0330070fd38ec3bb94f58fa55d40368271e9e54a, claimed to be owned by Jan de Vries from the Netherlands, is on any OFAC sanctions or PEP lists? The owner is a person.

## When to prefer this

Use this endpoint when you need a lightweight, pay-per-call compliance check for a specific self-hosted crypto wallet and its claimed owner against OFAC and PEP lists without setting up a full KYC infrastructure. Ideal for onboarding flows, pre-payment vendor screening, or periodic re-screening of existing counterparties. Best when you need both wallet-level OFAC screening and owner-level PEP/sanctions screening in a single call.

## Known failure modes

- Missing required 'wallet' or 'owner' query parameters returns a 400 error
- Invalid wallet address format may return no matches or an error
- Unknown or unsupported country code may degrade match quality
- Name-only matching may produce false positives or missed hits for common names without birth_year
- Service unavailability or upstream list refresh lag may affect freshness of results

## How this service works

Crypto wallet sanctions check and self-hosted wallet evidence (OFAC, PEP). Use when a crypto service sends to or receives from a self-hosted wallet and must document its checks (EU AMLR, Travel Rule files): screens the wallet against OFAC-listed addresses, the claimed owner against EU, UN, UK and US sanctions and PEP, and checks the company register for businesses. Returns no_hits, review or block_review with list versions and a signed receipt. Input: wallet, owner, optional owner_type,...

## Output

A JSON object containing an outcome field (e.g. 'no_hits'), an evidence object with the wallet address and its OFAC status plus any matches, and the owner's PEP and sanctions screening results including match details. Also includes a timestamp of when the check was performed and a flags array for any issues found.
