    The function itself will have to perform the following steps:
    - make a HTTP GET call to the HTTP server at the URL `c.url` (`c` is the receiver of the `Get` function of our implementation type `client`) at the API endpoint `/api/get` using the `key` argument as the query id parameter value:
      ```go
-     r, err := http.Get(url.String())
+     r, err := http.Get(uri.String())
      ```
    - return an empty `api.VersionedValue{}` and an error if something goes wrong,
    - check if the return status is 200 (`http.StatusOK`) and return an empty `api.VersionedValue{}` and an error if not,
