# Current-period copilot usage rollup

`GET /api/copilot/usage`

## Request

- Base URL: `https://api.setluca.com`
- URL: `https://api.setluca.com/api/copilot/usage`
- Auth: API key in cookie `luca.session_token`

Ask Luca consumption for the current billing period: included units used, units left in top-up packs, overage units and what they cost, and the overage cap in force. A coach who set their own cap keeps it. The tier default only fills in for someone who never did.

**Session-only.** This endpoint isn't on the API-key allowlist. An organization API key gets a 403 here, whatever scopes it holds.
