@api_controller("/content")
class ContentController:
    # User must be authenticated AND have premium subscription
    @http_get("/premium", permissions=[IsAuthenticated() & HasPremiumSubscriptionAsync()])
    async def premium_content(self, request):
        return {"content": "Premium content"}
    
    # User must be authenticated OR an admin
    @http_get("/special", permissions=[IsAuthenticated() | IsAdminUser()])
