Scriptable first-pass SDN name screening. For wallet-address checks, use the live OFAC free tool or paid API.
See the local name screener →Resolve company names, tickers, and CIKs locally for scripts and batch jobs. It does not search Form D filings.
See the CIK resolver →Filter SEC 8-K entries by Item code, keyword, or event pack, with an offline sample and optional fetch.
See the 8-K CLI →For a broader offline workflow, the $29 OFAC Wallet Screening Kit checks OFAC-published crypto addresses, while the $19 SEC EDGAR Starter Kit combines CIK lookup, filings, 8-K Item extraction, and XBRL facts to CSV.
Every guide cites primary sources directly — OFAC's own site and data files, or the SEC's own EDGAR documentation and endpoints — rather than summarizing a third party's summary. Each one links to a matching free, no-signup tool on this site that does the live lookup, and a "Do it via API" section with the exact x402 (pay-per-call USDC), MCP, and RapidAPI calls if you want to automate the same lookup.
