The claim, the stop and the ship are ONE settlement for the same reason a retirement is — the snapshot that carries the advanced watermark has to carry the new state, or a successor hydrates a running row for a pod that is gone and bills for it until the reaper notices. ## Request 1 field. | Field | In | Type | Required | Description | | ----- | ---- | ------ | -------- | -------------------------------------------- | | `id` | path | string | yes | ID is the sandbox to address, from the path. | ## Response | Status | Body | Meaning | | --------- | --------------- | ------- | | `200` | sandbox.Sandbox | ok | | `default` | problem-details | refused | `200` body — 16 fields. | Field | In | Type | Always | Description | | ------------- | ---- | --------------- | ------ | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | `actor` | body | string | — | Actor is the subject who LEASED this sandbox — the validated caller of the act that took the lease, never a value a request supplied. | | `class` | body | string | — | Class is what the sandbox is FOR, and it decides the image, the working directory and the isolation: "exec" for a code-interpreter call (workdir /mnt/data, no project, bounded per org), "dev" for a workspace bound to a project (workdir /work, single-attach), "desktop" for one with a screen. | | `cluster` | body | string | — | Cluster is the attached cluster this sandbox runs on — the fleet-local name the lease named — or empty for the home cluster. | | `connectedAt` | body | integer (int64) | — | ConnectedAt is when somebody was last known to have this sandbox's project OPEN, Unix seconds. | | `createdAt` | body | integer (int64) | — | CreatedAt is when the lease was taken, Unix seconds — by the lease that made the sandbox, and again by each resume, which gives a parked sandbox a new pod on a new lease. | | `error` | body | string | — | Error is why the sandbox could not come up, in plain words. | | `expiresAt` | body | integer (int64) | — | ExpiresAt is when the lease ends, Unix seconds. | | `id` | body | string | — | ID is the sandbox's server-minted handle and what every operation addresses it by. | | `image` | body | string | — | Image is the container image this sandbox is actually running — the one the class chose, or an override the policy admitted. | | `kind` | body | string | — | Kind is the resource family this row belongs to. | | `lastUsedAt` | body | integer (int64) | — | LastUsedAt is when the sandbox last did work, Unix seconds. | | `org` | body | string | — | Org is the org that holds the lease — the validated caller's, never a value a request supplied. | | `project` | body | string | — | Project is the project this sandbox is bound to. | | `runtime` | body | string | — | Runtime is the isolation boundary this sandbox GOT, which is not always the one it asked for: a caller states a preference and runtimeFor answers with what the sandbox can actually have. | | `status` | body | string | — | Status is where the sandbox is in its life: "pending" while the pod is coming up, "running" once it can take work, "error" when it cannot, and "parked" when its pod is stopped and its disk kept, until a resume. | | `volume` | body | string | — | Volume is the persistent volume attached to the sandbox, when it has one. | Failure carries the platform error shape — see [Errors](https://docs.hanzo.ai/docs/errors). ## Examples **CLI** ```bash hanzo sandbox pause ``` **SDK** **.ts** ```ts import { Configuration, SandboxApi } from 'hanzoai'; const api = new SandboxApi(new Configuration({ accessToken: process.env.HANZO_API_KEY })); const { data } = await api.postSandboxByIdPause({ id: 'id' }); ``` **.py** ```python from hanzoai.cloud import ApiClient, Configuration from hanzoai.cloud.api import SandboxApi client = ApiClient(Configuration(access_token=os.environ["HANZO_API_KEY"])) result = SandboxApi(client).post_sandbox_by_id_pause(id='id') ``` **.go** ```go cfg := hanzoai.NewConfiguration() cfg.AddDefaultHeader("Authorization", "Bearer "+os.Getenv("HANZO_API_KEY")) client := hanzoai.NewAPIClient(cfg) resp, _, err := client.SandboxAPI.PostSandboxByIdPause(context.Background()).Execute() if err != nil { return err } ``` **.rs** ```rust use hanzo_client::apis::{configuration::Configuration, sandbox_api}; let mut cfg = Configuration::new(); cfg.bearer_access_token = std::env::var("HANZO_API_KEY").ok(); let result = sandbox_api::post_sandbox_by_id_pause(&cfg, Default::default()).await?; ``` **.java** ```java import ai.hanzo.cloud.ApiClient; import ai.hanzo.cloud.api.SandboxApi; ApiClient client = new ApiClient(); client.setBearerToken(System.getenv("HANZO_API_KEY")); var result = new SandboxApi(client).postSandboxByIdPause(); ``` **HTTP** ```bash curl -X POST https://api.hanzo.ai/v1/sandbox//pause \ -H "Authorization: Bearer $HANZO_API_KEY" ``` **MCP** MCP reaches **sandbox** through the `sandbox` tool, which names its 17 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_sandboxes" } } }' ``` --- [Sandbox API](https://docs.hanzo.ai/docs/openapi/sandbox) · [All Hanzo APIs](https://docs.hanzo.ai/docs/openapi) · [Interactive reference](https://docs.hanzo.ai/docs/openapi/reference)
