# Get workspace token usage

GET https://api.athenaintel.com/api/v0/workspaces/{workspace_id}/usage

Aggregate LLM token usage (and cost) for one workspace over the last `days` days: workspace totals plus per-member, per-day and per-Computer breakdowns. Token counters are summed from each session's usage ledger; dry-run (test) sessions are reported separately and excluded from the totals. Requires workspace owner or manager (or Athena admin) permissions — the same gate as the in-app Usage page.

Reference: https://docs.athenaintel.com/api-reference/workspaces/get-usage

## Authentication

- `X-API-KEY` header (required) — API Key authentication via header

## Request

### Path parameters

- `workspace_id` (string, required)

### Query parameters
