The Consolidated Screening List is free and official, and 1Lookup returns a screening verdict for $0.015 a name.

Screening potential buyers and end-users against US government restrictions. The International Trade Administration describes it as a list of parties for which the United States Government maintains restrictions on certain exports, reexports or transfers of items, consolidating lists of the Departments of Commerce, State and the Treasury. It comes as a search engine, downloadable CSV, TSV and JSON files, and an API.

It is free. The pages read print no plan, quota or charge, and the page says the API 'enables computers to freely access the CSL in an open, machine-readable format'. The API needs a subscription key: you create a developer portal account, subscribe once and send the key with each request. The service level agreement says the throttling level of each API is on that API's documentation page. Checked October 2026.

3 credits per completed screening, billed for every completed screening, a clear one included. On the Starter plan ($99 a month for 20,000 credits) a screening is about $0.015, which covers 6,666 names a month and is $14.85 per 1,000. At the Enterprise end of the rate card it is about $0.006. The Consolidated Screening List is the cheaper bill: it is free, against $99 for a Starter month.

A search returns the matching records with a score, and the terms say the International Trade Administration 'does not provide endorsements or recommendations with regard to any specific CSL search result or score', so deciding what counts as a hit is up to you. 1Lookup returns a verdict of clear, possible match or match, the recommended action, and up to ten matches ranked strongest first. It ignores company endings such as Inc and Ltd, tolerates small spelling differences and shows each match's list, agency, programs, aliases and addresses.

On price and on control. It is free. Its API filters by 13 source codes, by entry type (aircraft, entity, individual or vessel), by country and by address fields, and returns up to 50 results a request. The whole list downloads as CSV, TSV or JSON, and the service level agreement states 99.5% uptime. 1Lookup takes a name and an optional country, returns at most ten matches and cannot search by address.

No. 1Lookup screens 12 US government lists across Treasury, Commerce and State, and the Consolidated Screening List API offers 13 source filters. Neither includes EU, UN, UK or other countries' lists. If you need those, compare a provider that covers them, such as OpenSanctions or ComplyAdvantage.

The International Trade Administration says its tools are updated automatically every day at 5:00 AM EST/EDT, pulling each agency's latest file. 1Lookup refreshes its copy of the list every 6 hours and puts the list's update date in every answer. When the lists cannot be read, the request fails without a charge and is never answered as clear. A repeat of the same screening by the same user within 24 hours comes from the cache at no charge.

For the Consolidated Screening List API: a developer portal account, a subscription to its Data Services Platform APIs product and the key from your profile page, then your own code to call the search operation and read the scores. For 1Lookup: one API key, with a 7-day free trial, and the same key and balance that pay for phone, email and IP checks. A CSV with a name column screens a whole list in one job.

If you want the government's own consolidated list for nothing and can read a scored result, the Consolidated Screening List is hard to beat. If you want a clear, possible match or match answer for each name, with ranked matches and bulk CSV files and no portal account, 1Lookup's Sanctions Screening bills 3 credits for every completed screening.

Yes, if you want the official list at no cost and have someone to run the searches and judge the scores: it is free, updated daily and filterable. It only holds active entries, so the documentation points to the source agencies for historical research. If you want an answer per name without building the matching and scoring around it, compare the per-screening price of 1Lookup.
