## Routing

| User Intent | Workflow |
|-------------|----------|
| Understand current costs | [Cost Query](cost-query/workflow.md) |
| Reduce costs / find waste | [Cost Optimization](cost-optimization/workflow.md) |
| Project future costs | [Cost Forecast](cost-forecast/workflow.md) |

## Quick Reference

| Property | Value |
|----------|-------|
| **Query API** | `POST {scope}/providers/Microsoft.CostManagement/query?api-version=2023-11-01` |
| **Forecast API** | `POST {scope}/providers/Microsoft.CostManagement/forecast?api-version=2023-11-01` |
| **Required Role** | Cost Management Reader + Monitoring Reader + Reader (on target scope) |

## Scope Patterns

- Subscription: `/subscriptions/<id>`
- Resource Group: `/subscriptions/<id>/resourceGroups/<name>`
- Management Group: `/providers/Microsoft.Management/managementGroups/<id>`
- Billing Account: `/providers/Microsoft.Billing/billingAccounts/<id>`
