Product Docs: Billing Center
Access Akamai contract usage data for accounts which you have access to.
Billing Center gives you access to your website’s monthly usage over the Akamai network. With Billing Center, you can develop your own visualizations using JSON data. A range of data is available, including number of hits, megabytes served, and transmission speed. You can also use this API to compare usage data with your billing invoice.
If you want to develop your own tools to track invoice files, and keep others updated about their status, use the Invoicing API.
