  -H "X-Stratum-Key: $STRATUM_KEY"

The company and everyone recorded in its ownership at Companies House, screened against the same ten lists, with a verdict for each set of rules you ask for: the UK test (more than 50% or control), the US export rules’ 50% rule for Entity List and Military End User owners, OFAC’s 50% rule (SDN owners) and the EU test. Each verdict says owned or controlled, may reach the threshold, none, or not checked, and the result says where the record stops.

Up to 20 parties by role (buyer, consignee, end user, intermediate consignee, forwarder, supplier), each a name or a UK company number, plus what GOV.UK lists for the destination and the US country controls in 15 CFR Part 746. One check for each party screened; a party that couldn’t be screened isn’t charged and the result says incomplete, never clear. Nothing is stored: the response is your record.

• GET /v1/export-screening/destinations/{country}: a destination’s UK and US measures, free.
• POST /v1/export-screening/bulk: up to 100 names a request.
• A watchlist re-screened every morning, and GET /v1/export-screening/changes for each day’s additions to and removals from the US export lists.

A screening record, not a licensing decision: whether goods need a licence depends on what they are, where they go and their end use.

• The export screening docs and the OpenAPI file.
• Why UK trade software needs the Entity List and UK sanctions in one screen.
• For people rather than code, the same checks are on Certaby.
