How to get aggregated values using Power BI report server rest API?

[saranrajk]

Hi, 

I'm trying to get aggredated value from the shared data using using the following API url.

http://localhost/reports/api/v2.0/DataSets(dataset_id)/Model.GetAggregatedValue?ColumnName=ingredient_price&Aggregation=sum

Nothing is working for me regarding Model.

for example model.getdata is also not working

http://localhost/reports/api/v2.0/DataSets(dataset id)/Model.GetData

and I'm getting the error in attached image.

what is Model?

and for /dependentitems 

http://d2n3kzl2//reports/api/v2.0/DataSets(dataset id)/DependentItems

I am getting the following error

{
  "error":{
    "code":"","message":"No HTTP resource was found that matches the request URI 'http://d2n3kzl2/reports/api/v2.0/DataSets(7af2bc9a-738d-47f9-a1da-2a182d0b8509)/DependentItems'."
  }
}

How to resolve this too?

Thanks in Advance
