The Billing page allows you to manage your ActumX account credits, top up your balance, and review payment history. This section handles all financial aspects of using the platform.

​
Credit Balance Overview

The main Billing page displays your account’s credit management interface.

​
Billing Cards

The page is organized into three main sections:
  1. Billing - Overview and description
  2. Top Up Credits - Add credits to your account
  3. Recent Top Ups - Payment history table

​
Viewing Credit Balance

Your current credit balance is reflected through your payment history and usage. Credits are consumed as your agents make API requests and transactions via the x402 protocol.

​
Credit System

ActumX uses a credit-based billing system:
  • Credits are denominated in cents (USD)
  • Example: 2500 credits = $25.00
  • Credits are deducted based on API usage
  • Low balance alerts help prevent service interruption

​
Topping Up Credits

​
Top Up Process

  1. Navigate to the “Top Up Credits” section
  2. Enter the amount in cents (not dollars)
  3. Click “Top Up” button
  4. Wait for confirmation

​
Amount Input

Format: Enter amount in cents
  • Minimum: 100 cents ($1.00)
