chainpeek: the sanctions screen for 1-1,000 crypto addresses in one call: per address matched, address_kind and the matching SDN entries (name, type, programs, currency), plus matched_count, the list date and a disclaimer. Input: addresses (1-1,000, each 1-128 characters: EVM 0x, bech32, or BTC/TRX/other as listed). EVM and bech32 addresses match case-insensitively; base58 BTC, TRX and other formats must match exactly as listed. Screening against the US OFAC SDN digital-currency-address list only (the Treasury SDN list's published crypto addresses), as of the list_date in the answer; a non-match does not clear an address; not legal advice or a full compliance check (no other sanctions lists, no clustering, ownership or exposure analysis); verify any match at sanctionssearch.ofac.treas.gov. One invalid item fails the whole batch with a 422 naming its index (not charged). Typically under 0.5 s for 1,000 addresses. Price: USD 0.0005 per address, at least USD 0.002 per call (1-1,000 addresses per call: USD 0.002-0.5). No free tier (URL and sanctions batches are never free).
