- URL: `https://meetkatalis.com/api/v1/aml-register`

Matched on the business's name as the register writes it (a company number brings its registered and former names), with the register's postcode district checked against the registered office. Current registrations with sectors and status (Approved, Applied, Expired), former ones with the date they went, and every change recorded for the name since 7 October 2026. HMRC is one supervisor among several, so absence never means unsupervised. People never loaded. 1 credit.
