List instance counters for an accounting window. Legacy fixed-scope budgets return one pooled row with an empty instance_key. Omit window to use the current window. Use split_dim to keep only counters that match every given dimension value.

## Path parameters

- `id` string, uuid, required

## Query parameters

- `window` string, date-time
- `split_dim` string[]
- `sort` 'spend_desc' | 'spend_asc' | 'key_asc': Sort order for budget instance counters.
- `limit` integer
- `offset` integer

## Response `200`
