## Path parameters

- `kg_id` string, uuid, required

## Request body

Successful Response

- SubscriptionResponse
  - `package_slug` string, required
  - `package_version` string, required
  - `enabled_at` string, date-time, required
  - `in_scope` boolean, required — False when the subscription's (slug, version) no longer resolves to a Package in code — e.g., the Package was removed. Surfaces the deprecation-as-not-in-scope behaviour to clients.
