Examples **CLI** ```bash hanzo o11y sentinel traces get --project ``` **SDK** **.ts** ```ts import { Configuration, O11yApi } from 'hanzoai'; const api = new O11yApi(new Configuration({ accessToken: process.env.HANZO_API_KEY })); const { data } = await api.getO11ySentinelTracesById({ id: 'id', project: 'project' }); ``` **.py** ```python from hanzoai.cloud import ApiClient, Configuration from hanzoai.cloud.api import O11yApi client = ApiClient(Configuration(access_token=os.environ["HANZO_API_KEY"])) result = O11yApi(client).get_o11y_sentinel_traces_by_id(id='id', project='project') ``` **.go** ```go cfg := hanzoai.NewConfiguration() cfg.AddDefaultHeader("Authorization", "Bearer "+os.Getenv("HANZO_API_KEY")) client := hanzoai.NewAPIClient(cfg) resp, _, err := client.O11yAPI.GetO11ySentinelTracesById(context.Background()).Execute() if err != nil { return err } ``` **.rs** ```rust use hanzo_client::apis::{configuration::Configuration, o11y_api}; let mut cfg = Configuration::new(); cfg.bearer_access_token = std::env::var("HANZO_API_KEY").ok(); let result = o11y_api::get_o11y_sentinel_traces_by_id(&cfg, Default::default()).await?; ``` **.java** ```java import ai.hanzo.cloud.ApiClient; import ai.hanzo.cloud.api.O11yApi; ApiClient client = new ApiClient(); client.setBearerToken(System.getenv("HANZO_API_KEY")); var result = new O11yApi(client).getO11ySentinelTracesById(); ``` **HTTP** ```bash curl https://api.hanzo.ai/v1/o11y/sentinel/traces/?project=%3Cproject%3E \ -H "Authorization: Bearer $HANZO_API_KEY" ``` **MCP** MCP reaches **o11y** through the `o11y` tool, which names its 307 operations with its own verbs — this one among them, under a name only MCP declares. `describe` explains any of them: ```bash curl -X POST https://api.hanzo.ai/v1/mcp \ -H "Content-Type: application/json" \ -d '{ "jsonrpc": "2.0", "id": 1, "method": "tools/call", "params": { "name": "describe", "arguments": { "op": "list_o11y_autocomplete_aggregate_attributes" } } }' ``` --- [O11y API](https://docs.hanzo.ai/docs/openapi/o11y) · [All Hanzo APIs](https://docs.hanzo.ai/docs/openapi) · [Interactive reference](https://docs.hanzo.ai/docs/openapi/reference)
