agent briefs list ``` **SDK** **.ts** ```ts import { Configuration, AgentApi } from 'hanzoai'; const api = new AgentApi(new Configuration({ accessToken: process.env.HANZO_API_KEY })); const { data } = await api.getAgentBriefs(); ``` **.py** ```python from hanzoai.cloud import ApiClient, Configuration from hanzoai.cloud.api import AgentApi client = ApiClient(Configuration(access_token=os.environ["HANZO_API_KEY"])) result = AgentApi(client).get_agent_briefs() ``` **.go** ```go cfg := hanzoai.NewConfiguration() cfg.AddDefaultHeader("Authorization", "Bearer "+os.Getenv("HANZO_API_KEY")) client := hanzoai.NewAPIClient(cfg) resp, _, err := client.AgentAPI.GetAgentBriefs(context.Background()).Execute() if err != nil { return err } ``` **.rs** ```rust use hanzo_client::apis::{configuration::Configuration, agent_api}; let mut cfg = Configuration::new(); cfg.bearer_access_token = std::env::var("HANZO_API_KEY").ok(); let result = agent_api::get_agent_briefs(&cfg, Default::default()).await?; ``` **.java** ```java import ai.hanzo.cloud.ApiClient; import ai.hanzo.cloud.api.AgentApi; ApiClient client = new ApiClient(); client.setBearerToken(System.getenv("HANZO_API_KEY")); var result = new AgentApi(client).getAgentBriefs(); ``` The method above is the one at the current release of the document. `hanzoai@8.5.914` (npm) and `hanzoai@8.5.914` (PyPI) were generated from an earlier release, where this operation carried a different id, so it spells the method differently — regenerating the clients is what makes the two agree.
