CheckBiz.eu is a European company-verification and brand-protection service operated by AddonNordic ApS (Denmark, CVR 46495985). Brand Watch scans for copycat websites of an online store and files takedown requests with registrars, hosts and payment providers (from EUR 39/month); the company check returns a report on any European company from official national business registers, EU VIES, GLEIF and public sanctions lists (EUR 1.99). Merchant Check lets AI shopping agents verify, via a REST API (api.checkbiz.eu/v1/merchant-check) or a remote MCP server with a check_merchant tool, that a shop's domain belongs to a registered, active EU company.
