const api = new StudioApi(new Configuration({ accessToken: process.env.HANZO_API_KEY })); const { data } = await api.getStudioRunsByIdVersions({ id: 'id' }); ``` **.py** ```python from hanzoai.cloud import ApiClient, Configuration from hanzoai.cloud.api import StudioApi client = ApiClient(Configuration(access_token=os.environ["HANZO_API_KEY"])) result = StudioApi(client).get_studio_runs_by_id_versions(id='id') ``` **.go** ```go cfg := hanzoai.NewConfiguration() cfg.AddDefaultHeader("Authorization", "Bearer "+os.Getenv("HANZO_API_KEY")) client := hanzoai.NewAPIClient(cfg) resp, _, err := client.StudioAPI.GetStudioRunsByIdVersions(context.Background()).Execute() if err != nil { return err } ``` **.rs** ```rust use hanzo_client::apis::{configuration::Configuration, studio_api};
