OFAC sanctions screening: crypto wallet or name API

OFAC sanctions (AML/KYC) screening of a crypto wallet or a person, company, vessel or aircraft name against a dated snapshot of the U.S. Treasury SDN and non-SDN Consolidated lists. Address mode: exact match on OFAC-listed digital currency addresses (BTC, ETH/EVM, USDT, TRX, XMR, LTC, more). Name mode: fuzzy match on names and strong aliases ignoring case, accents, punctuation and word order, scored 0-100. Returns match flag, OFAC uid, type, programs, country, list date.

$0.01 per call USDC over x402 v2 on Base, Polygon, Arbitrum, Avalanche or Sei. No signup, no API key. Requests that fail or match nothing are not charged.

Parameters

Name	Type	Required	Description
`address`	string	no	Crypto wallet address (20 to 120 characters) checked for an exact match against OFAC-listed digital currency addresses; EVM 0x, bech32 and CashAddr addresses match case-insensitively (bitcoincash: prefix optional). Mutually exclusive with name. e.g. `0x098B716B8Aaf21512996dC57EB0615e2383E2f96`
`name`	string	no	Person, company, vessel or aircraft name, 2 to 120 characters, in Latin script; case, accents, punctuation and word order are ignored. Mutually exclusive with address. e.g. `Vladimir Putin`
`threshold`	integer	no	Minimum name match score from 70 to 100 (default 85); the score mainly reflects how closely every query word matches a word of the listed name. Name mode only. e.g. `85`
