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.
Example use cases
Pre-payment sanctions screening
“Before I send crypto to 0xAbCd1234...5678, can you verify it's not on the OFAC SDN list or any other sanctions list?”
Compliance check for DeFi integration
“We're building a DeFi onboarding flow — can you check whether wallet address TRXabc123xyz is flagged by any sanctions programme so we can block it if needed?”
Investigating a suspicious counterparty
“I received a payment from this Monero address and want to know if it's sanctioned by the US government or listed on any official watchlist.”
Technical details
Endpoint
GEThttps://factline.dev/v1/sanctions/wallet?utm_source=zero.xyzWhen to prefer
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.
Side effects
- 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
