Get Item Details using API with default buyer filter

Summary:

Looking to fetch the item information at org level by using the filter of default buyer

Content (please ensure you mask any confidential information):

The /fscmRestApi/resources/11.13.18.05/itemsV2 REST API endpoint is designed to retrieve item data but with atleast one of the following filters : ItemNumber, ItemDescription, or Keyword. Our requirement consists of having only the default buyer value ('****') as an input, and to get the list of items which have '****' as default buyer assigned at all orgs.

Need advice on methods available to get item information based on above filter. Thanks.
