To get instrument usage, You can use this endpoint (https://selectapi.datascope.refinitiv.com/RestApi/v1/Usage/GetExtractionUsageInstrumentSummar) with the HTTP Post method. The body of a request message contains:

{
    "ExtractionUsageCriteria": {
        "StartDateTime": "2021-01-01T00:00:00Z",
        "EndDateTime": "2021-11-01T00:00:00Z"
        
    }
}

The output is:

{
    "@odata.context": "https://selectapi.datascope.refinitiv.com/RestApi/v1/$metadata#DataScope.Select.Api.Usage.ExtractionUsageInstrumentSummaryResult",
    "Records": [
        {
            "AssetClass": "BMRK",
            "SubClass": "NONE",
            "ReportTemplate": "IDP",
            "SubTemplate": "NONE",
            "Count": 2,
            "EquityFairValue": 0,
            "FixedIncomeValuations": 0
        },
        {
            "AssetClass": "CHR",
            "SubClass": "NONE",
            "ReportTemplate": "THT",
            "SubTemplate": "NONE",
            "Count": 1695,
            "EquityFairValue": 0,
            "FixedIncomeValuations": 0
        },

The Java code generated by Postman is:

Unirest.setTimeouts(0, 0);
HttpResponse<String> response = Unirest.post("https://selectapi.datascope.refinitiv.com/RestApi/v1/Usage/GetExtractionUsageInstrumentSummary")
  .header("Prefer", "respond-async")

  .asString();

The C# code generated by Postman is:

var client = new RestClient("https://selectapi.datascope.refinitiv.com/RestApi/v1/Usage/GetExtractionUsageInstrumentSummary");
client.Timeout = -1;
var request = new RestRequest(Method.POST);
request.AddHeader("Prefer", "respond-async");
request.AddHeader("Content-Type", "application/json");
request.AddHeader("Authorization", "Token <token>");
var body = @"{

@"}";
request.AddParameter("application/json", body,  ParameterType.RequestBody);
IRestResponse response = client.Execute(request);
Console.WriteLine(response.Content);

The C# code with DSS .NET SDK is:

using DataScope.Select.Api.Usage;
...
Uri dssUri = new Uri("https://selectapi.datascope.refinitiv.com/RestApi/v1/");
var context = new UsageContext(dssUri, dssUserName.Value, dssPassword.Value);
var result = context.GetExtractionUsageInstrumentSummary(new ExtractionUsageInstrumentSummaryCriteria
{
    StartDateTime = DateTime.UtcNow - TimeSpan.FromDays(120),
    EndDateTime = DateTime.UtcNow
});
foreach(var rec in result.Records)
{
    Console.WriteLine($"AssetClass: {rec.AssetClass}");
    Console.WriteLine($"SubClass: {rec.SubClass}");
    Console.WriteLine($"ReportTemplate: {rec.ReportTemplate}");
    Console.WriteLine($"Count: {rec.Count}");
    Console.WriteLine($"EquityFairValue: {rec.EquityFairValue}");
    Console.WriteLine($"FixedIncomeValuations: {rec.FixedIncomeValuations}\n");
}
