How this service works
Direct wallet sanctions exposure check on Base. Screens a wallet and a bounded set of recent transfer counterparties, with evidence, coverage, and explicit limitations.
Output
Returns a verdict (sanctioned or not_listed) for the target wallet, a list of counterparty matches with interaction direction (sent_to, received_from, bidirectional), sanctions match details (name, sanctioned_at, listed blockchain), coverage metadata, the sanctions lists consulted, cache status, timestamp, recommended action, and explicit limitations of the check.
Example use cases
Example prompt
“Can you run a sanctions exposure check on the Base wallet 0xAbCd1234567890abcdef1234567890abcdef1234 — I need to know if it's directly sanctioned and whether any recent transfer counterparties are on sanctions lists before I proceed?”
Technical details
Endpoint
GEThttps://wallet-sanctions.use.x402atlas.com/exposureWhen to prefer
Use this endpoint when you need a structured, evidence-backed sanctions screening of a specific Base mainnet wallet with counterparty exposure context — particularly for compliance workflows, pre-payment due diligence, or AML checks on Base. Prefer this over generic blockchain explorers when you need a direct sanctions verdict with list citations, interaction direction, and explicit coverage/limitation disclosures in a single API call.
Side effects
- Invalid or malformed wallet address (not 42 chars or not 0x-prefixed) returns validation error
- Unsupported network (non-Base) returns enum validation error
- Address with no transaction history may return empty counterparty matches with limited coverage
- Rate limiting or payment failure may block the request
- Cached results may not reflect the most recent sanctions list updates
