## How to call it through Zero

```sh
zero fetch --capability factline-sanctions-wallet-check-b6097773
```

Example prompt: Can you check if the wallet address 0x0330070fd38ec3bb94f58fa55d40368271e9e54a is on any government sanctions list before I proceed with this transaction?

## When to prefer this

Use this endpoint when you need a fast, per-wallet sanctions screening against official government lists (especially US OFAC SDN) for a broad range of blockchain address formats. It supports Bitcoin, Ethereum/EVM, Tron, Litecoin, Monero, and USDT addresses in a single unified API, making it ideal for compliance automation, pre-payment screening, and AML workflows without needing to integrate directly with raw government data feeds.

## Known failure modes

- Missing 'address' query parameter returns a validation error
- Unsupported address format may return no matches rather than an error
- Stale list data if the sanctions list was not recently refreshed (check 'loaded_at' timestamp)
- Address not found returns sanctioned: false with an empty matches array
- Network or payment (x402) errors may prevent the call from completing

## How this service works

API and MCP servers that let AI agents and apps check people, companies, Dutch addresses and cars against official records: sanctions and PEP lists, 10 company registers, Dutch property, rent and RDW vehicle data. From $0.001 per call.

## Output

Returns a JSON object with the queried wallet address, the sanctions list metadata (name and load timestamp), a boolean 'sanctioned' field, and an array of matches — each containing the list(s) matched, currency, a reference code, the sanctioning programme(s), and the name of the listed entity.
