Castle API

Castle's REST API for real-time fraud and abuse detection. The Risk API scores authenticated user events (login, transaction, profile update), the Filter API scores anonymous/pre-authentication events (registration, password reset), the Log API records events without scoring, and the enterprise Events API queries and aggregates historical events. Device and Lists endpoints manage device reputation and allow/deny lists.
