AgeKit+ is k-ID’s standalone age-verification product for applications that need age verification without the broader parental-consent and permission-management features of its Compliance Development Kit. It supports a configured waterfall flow, where one API call presents verification methods in sequence, and a single-method flow, where developers choose methods through method-specific endpoints. Available methods can include facial age estimation, ID document verification, AgeKey, credit-card verification, email age estimation, and regional options. The verification flow returns a URL for users to complete the process.
