Azure REST API - Where do I find resource costs? - azure

Question

I'm looking at the documentation of the rest API and I'm looking to get the costs of my resources.
Looking at both the REST API and SDK for .NET, there's a Consumption endpoint that does this, but on further testing, this only seems to provide the latest available billing cycle (24 hour window).
Example Code:
var filterString = $"properties/instanceName eq \'{vm.VirtualMachineName}\'";
var vmConsumptionData = await consumptionClient.Item1.UsageDetails.ListAsync(
scope: $"/subscriptions/{consumptionClient.subscriptionGuid}",
filter: filterString
);
consumptionClient is an instance of a consumptionClient returned as part of a Tuple elsewhere.
Result is yesterdays last billed amount.
Are there any other endpoints that would provide a more up to date cost overview of my resources in Azure? I.E. Per minute or hour
The only other way I believe this can be done is to retrieve the 'Usage quantity' of a resource and work this out based on the resources cost per hour.

As of Mar-06-2020 documentation on Microsoft.CostManagement/Query worked:
POST https://management.azure.com/subscriptions/{subscriptionId}/resourcegroups/{resourceGroupName}/providers/Microsoft.CostManagement/query?api-version=2019-11-01&$top=10000
Content-Type: application/json
{
"type": "ActualCost",
"dataSet": {
"granularity": "None",
"aggregation": {
"totalCost": {
"name": "PreTaxCost",
"function": "Sum"
},
"totalCostUSD": {
"name": "PreTaxCostUSD",
"function": "Sum"
}
},
"filter": {
"Dimensions": {
"Name": "ResourceId",
"Operator": "In",
"Values": [
"{resourceId}"
]
}
}
},
"timeframe": "Custom",
"timePeriod": {
"from": "2020-02-29T00:00:00+00:00",
"to": "2020-03-06T23:59:59+00:00"
}
}
with response:
{
"id": "subscriptions/{subscriptionId}/resourcegroups/{resourceGroupName}/providers/Microsoft.CostManagement/query/XXXXXXXX-9ab4-XXXX-83fe-XXXXXXXXXXXX",
"name": "XXXXXXXX-9ab4-XXXX-83fe-XXXXXXXXXXXX",
"type": "Microsoft.CostManagement/query",
"location": null,
"sku": null,
"eTag": null,
"properties": {
"nextLink": null,
"columns": [
{
"name": "PreTaxCost",
"type": "Number"
},
{
"name": "Currency",
"type": "String"
}
],
"rows": [
[
1234.5678910,
"CAD"
]
]
}
}
I found this returns accurate value for my specific resource.
NOTE: Only concern is that this API endpoint is flagged as -legacy in the documentation. Not sure if it will be supported long term but works for now.
