# How much the deployment was used since a time

GET

/v1/license/usage

```sh
curl --request GET \

  --header 'Authorization: Bearer <token>'
```

What a free license key’s renewal carries (`kindgi license renew --runtime`): the runs started since `since` (not dry runs, replays, evals or child runs), the distinct people who started runs or decided approvals (counted in each tenant and summed, so a person in two tenants counts twice), the projects in production when the runtime can put projects in production (`PUT /v1/projects/{projectId}/production`), and the runtime’s version. Counts only: no content, names or ids. Only the deployment’s own token (`KINDGI_API_TOKEN`), or a system key holding `system:license`, reads it; anyone else is refused (`license-operator-only`), and the refusal recorded, before `since` is read. A deployment that doesn’t report it answers 404.

## Authorizations

- **[bearerAuth](https://docs.kindgi.com/v0.1.8/reference/api.md#bearerauth)**

## Parameters

### Query Parameters

**since**

required

string format: date-time

The period’s start (ISO 8601, with a zone): `kindgi license renew` sends when the current key was issued. Up to five minutes ahead of the runtime’s clock is taken as now, since clocks differ; further ahead is refused.

## Responses
