Pricing Policy Examples​

Employee / Guest Pricing Policies​

import future.keywords.if

# Default to deny unless explicitly allowed
default allow = false

# Allow employees - they get free charging
allow if {
  input.user.type == "employee"
}

# Allow guests - they will be charged
allow if {
  input.user.type == "guest"
}

# Billing strategy: free for employees, standard for guests
billing_strategy := "free" if {
  input.user.type == "employee"
}

billing_strategy := "guest_billing" if {
  input.user.type == "guest"
}

# Contextual metadata about the decision
context := {
  "policy": "employee_guest",
  "user_type": input.user.type,
  "payment_method": input.user.payment_method,
  "timestamp": input.timestamp
}

# Denial reason for registered customers or other user types
denial_reason := "Access denied: Only employees and guests are permitted" if {
  not allow
}

Enforce Preauthorization Limits for Different Users​

package authorization.spending_limits

import future.keywords.if

default allow = false

# Guests have a lower pre-auth limit ($50)
allow if {
  input.user.type == "guest"
  input.pre_auth_amount <= 5000  # Assuming cents
}

# Registered customers have medium limit ($200)
allow if {
  input.user.type == "registered_customer"
  input.pre_auth_amount <= 20000
}

# Employees have no limit
allow if {
  input.user.type == "employee"
}

billing_strategy := "guest_billing" if {
  allow
  input.user.type == "guest"
}

billing_strategy := "customer_billing" if {
  allow
  input.user.type == "registered_customer"
}

billing_strategy := "free" if {
  allow
  input.user.type == "employee"
}

denial_reason := sprintf("Pre-authorization amount $%.2f exceeds limit for %s users", 
  [input.pre_auth_amount / 100, input.user.type]) if {
  not allow
}

Charger Specific VIP Access​

package authorization.vip_chargers

import future.keywords.if

default allow = false

vip_chargers := {
  "charger-vip-001",
  "charger-vip-002",
  "charger-executive-parking"
}

is_vip_charger if {
  vip_chargers[input.charger.charge_box_id]
}

# Only employees can use VIP chargers
allow if {
  is_vip_charger
  input.user.type == "employee"
}

# Everyone can use regular chargers
allow if {
  not is_vip_charger
}

billing_strategy := "free" if {
  allow
  is_vip_charger
  input.user.type == "employee"
}

billing_strategy := "standard" if {
  allow
  not is_vip_charger
}

context := {
  "policy": "vip_chargers",
  "is_vip_charger": is_vip_charger,
  "charger_id": input.charger.charge_box_id
}

denial_reason := "Access denied: VIP chargers are reserved for employees only" if {
  not allow
  is_vip_charger
}
