# Which system key this is

GET

/v1/system/whoami

```sh
curl --request GET \
  --url https://example.com/v1/system/whoami \
  --header 'Authorization: Bearer <token>'
```

A system key’s own id, scopes and expiry, for a service checking its key: any system principal, on a runtime serving many tenants. A tenant’s key or session is refused (`system-principal-required`). `GET /v1/identity/whoami` is a tenant route, which refuses a system key. A runtime serving one tenant answers no one here: its own token is that tenant’s outside `/v1/system/keys`, and a system key reads the license routes alone.
