Hosted Klarna Checkout (KCO), the checkout/v3 surface. Klarna divested the Klarna Checkout product and it now trades as Kustom; as of 2026-08-27 Klarna no longer publishes a dedicated Klarna Checkout reference on docs.klarna.com (https://docs.klarna.com/klarna-checkout/ returns 404) and lists Kustom among its acquiring partners instead. The checkout/v3 OpenAPI in this repo remains served from api.klarna.com.
