# Get billing breakdown

`GET /api/v1alpha/billing_breakdown`

Return per-(billing_project, user, resource) cost records for a date range. Billing managers (READ_ALL_BILLING_PROJECTS) see all records; other users see only rows where the user matches their own username. Costs are plain floats in USD. Rows with zero cost are excluded. The `resource` field uses internal resource names such as `"service-fee"`, `"compute/n1-standard/preemptible/us-central1"`, etc.
