What this capability serves is below, from the API document; what it is — the store it owns, how it meters, what it publishes — is written as a HIP under HIP-0139. ## Four surfaces | Surface | Reaches this capability as | Coverage | | -------- | ----------------------------------------------- | ------------------------------------------------------------------------- | | **REST** | `channel` at its own prefix | 9 operations | | **CLI** | `hanzo channel …` | 9 of 9 | | **SDK** | `ChannelApi` in every published client | 9 methods | | **MCP** | tool `channel` on `https://api.hanzo.ai/v1/mcp` | 8 operations, 4 under the document's own id — ask `describe` for the rest | ## Quickstart ```bash export HANZO_API_KEY=sk-... # console.hanzo.ai → API keys ``` Then the first call — a read that needs nothing but the key. `GET /v1/channel`, operation `get_channel`: **CLI** ```bash hanzo channel list ``` **SDK** **.ts** ```ts import { Configuration, ChannelApi } from 'hanzoai'; const api = new ChannelApi(new Configuration({ accessToken: process.env.HANZO_API_KEY })); const { data } = await api.getChannel(); ``` **.py** ```python from hanzoai.cloud import ApiClient, Configuration from hanzoai.cloud.api import ChannelApi client = ApiClient(Configuration(access_token=os.environ["HANZO_API_KEY"])) result = ChannelApi(client).get_channel() ``` **.go** ```go cfg := hanzoai.NewConfiguration() cfg.AddDefaultHeader("Authorization", "Bearer "+os.Getenv("HANZO_API_KEY")) client := hanzoai.NewAPIClient(cfg) resp, _, err := client.ChannelAPI.GetChannel(context.Background()).Execute() if err != nil { return err } ``` **.rs** ```rust use hanzo_client::apis::{configuration::Configuration, channel_api}; let mut cfg = Configuration::new(); cfg.bearer_access_token = std::env::var("HANZO_API_KEY").ok(); let result = channel_api::get_channel(&cfg, Default::default()).await?; ``` **.java** ```java import ai.hanzo.cloud.ApiClient;
