What the file says
# Azure Cost Management API
## The Problem
In PowerShell, inline JSON for Cost Management API causes "Unsupported Media Type" errors:
```powershell
# This fails silently or with 415 error
az rest --method POST --uri $uri --body '{"type":"Usage","timeframe":"MonthToDate"}'
```
The shell mangles the JSON.
## The Solution
Write JSON to a file, then reference with `@`:
```powershell
# 1. Create body file
$body = @{
type = "Usage"
timeframe = "MonthToDate"
dataset = @{
granularity = "Daily"
aggregation = @{
totalCost = @{
name = "Cost"
function = "Sum"
}
}
}
} | ConvertTo-Json -Depth 10
$bodyFile = "$env:TEMP\cost-query-body.json"
$body | Out-File -FilePath $bodyFile -Encoding utf8
# 2. Call with file reference
$uri = "/subscriptions/$subscriptionId/providers/Microsoft.CostManagement/query?api-version=2023-03-01"
az rest --method POST --uri $uri --body "@$bodyFile"
```
## Common Queries
### Monthly Cost by Resource Group
```json
{
"type": "Usage",
"timeframe": "MonthToDate",
"dataset": {
"granularity": "None",
"aggregation": {
