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.
Example use cases
Onboarding DeFi user compliance check
“Before we allow this new user onto our platform, can you run a sanctions and PEP check on their wallet 0xAbC1234...5678? They say their name is Maria Santos from Brazil and they're an individual, not a company.”
Corporate wallet vendor screening
“We're about to pay a supplier via their self-hosted wallet 0xDef9876...4321, owned by a company called NovaTrade BV in the Netherlands. Can you verify they're not on any sanctions list before we proceed?”
Periodic AML re-screening of existing wallets
“Re-check the compliance status of wallet 0x1a2b3c4d...ef owned by our client Ahmed Al-Rashid, born in 1975, from the UAE — I need to confirm he's still not flagged on any sanctions or PEP registry.”
Technical details
Endpoint
GEThttps://factline.dev/v1/wallet/evidence?utm_source=zero.xyzWhen to prefer
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.
Side effects
- 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
