IP risk check for signups, logins and checkouts (IPv4 and IPv6): is the address in an embargoed country (Iran, North Korea, Syria, Cuba) or a heavily sanctioned one, a botnet control server, a Tor exit node, an anonymous proxy, a VPN, or on a cloud or hosting network rather than a home or mobile connection? Returns the country and network owner and a low, medium or high risk level with every signal explained.

Crypto wallet screening before you pay or accept funds. Exact match against every OFAC-sanctioned address (all chains; a hit names the sanctioned party and SDN number), Tether's USDT freeze list on Tron, and wallets the FBI and victims' reports tied to major hacks (Bybit, Stake.com and more). Each result reported separately. Free sample: GET /sample/screen-address.

Sanctions screening for a person or company. Fuzzy name match (aliases and word order included) against the OFAC SDN, UN Security Council, EU, UK, Canadian, Swiss and Australian sanctions lists plus the US Consolidated Screening List (BIS Entity List, Denied Persons, Unverified and Military End-User lists; State Department nonproliferation and ITAR debarments; OFAC non-SDN lists), refreshed daily. Each hit gives the score, listed name, record ID, sanctions programmes, aliases and what matched, plus a field-by-field check of the date of birth, nationality and type you sent against the listed record; optional threshold and limit settings; each list's publication date for your audit record. Free sample: GET /sample/screen.

Field-by-field comparison (date of birth, nationality, entity type) for the strongest /screen hit. Now included in every /screen hit's 'comparison' at no extra cost; kept for existing integrations. Not charged if there's no hit to compare.

Email risk check for signups and payouts. Nine deterministic signals, no AI scoring: mail server (MX), disposable or throwaway domain, free-mail provider, domain age, certificate history, typo-squats of major providers, role accounts, mail provider and a mailbox probe. Returns a low, medium or high risk level with every signal explained.
