Usage

The Usage tab shows Carmen API call statistics for the selected workspace.

Workspace Usage

Without an API key filter, the chart shows total workspace usage for the selected date range.

API Key Filter

Selecting an API key narrows the view to calls made with that key. The Dashboard can compare the selected key usage with the workspace total so that the share of traffic is visible.

Date Range

Usage queries use date-only from and to filters in ISO date format:

from=2026-07-01&to=2026-07-06

The from and to dates may be the same day. If the current day option is enabled, the Dashboard keeps the to date at today's date and sends refreshed queries using that day.
