Getintent lets you use Report Biulder, which provides flexible adjustment to get the necessary reports with filtering and grouping.
To build an available inventory report, go to the "Reports Builder" tab in the interface and select the "available inventory" dataset:
Available inventory for domains

"Available inventory report" also allows you to see available inventory for in-banner video (IBV) traffic.
In order to do this, you must add the following filters to your report:

Estimating available native inventory requires additional filtering and grouping:
Image Native Assets (Grouping)
Lists all assets related to images, like Icon, Main Image, Logotype. Each image description is in [...] brackets.
Format of single image: [ {asset_type}; {size_type}; {size}; {opt/req} ], where:

[2;Min;25;25;opt] - [Asset type - LOGO; size_type - only minimal size is presented; minimal size - 25x25; Logo is an optional asset]
[3;Bounds;450-600x225-300;req] - [Asset type - Main Image; size_type - size can vary; size can vary within 450-600x225-300; Main image is required asset]
