Run a command in a sandbox
Runs a command inside the sandbox and returns its exit code, stdout and stderr.
POST /v1/sandbox/{id}/exec
| Address | https://api.hanzo.ai/v1/sandbox/{id}/exec |
| Method | POST |
| Operation | post_sandbox_by_id_exec |
| Auth | Authorization: Bearer $HANZO_API_KEY |
Runs a command inside the sandbox and returns its exit code, stdout and stderr. A non-zero exit is a SUCCESSFUL call carrying a failed program — the HTTP status stays 200, because "the tests failed" and "the sandbox is broken" are different facts.
NOTHING RUNS IN cloud. The command is streamed to the Kubernetes exec subresource of the sandbox's pod, which runs under the gVisor runtime class. The sandbox is addressed by pod NAME through the apiserver, never by address.

Response
The document declares no response body for this operation. It answers 200 on success and the platform error shape on failure — see Errors.
Examples
hanzo sandboxes exec <id>import { Configuration, SandboxApi } from 'hanzoai';
const api = new SandboxApi(new Configuration({ accessToken: process.env.HANZO_API_KEY }));
const { data } = await api.postSandboxByIdExec({ id: 'id' });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_exec(id='id')cfg := cloud.NewConfiguration()
cfg.AddDefaultHeader("Authorization", "Bearer "+os.Getenv("HANZO_API_KEY"))
client := cloud.NewAPIClient(cfg)
resp, _, err := client.SandboxAPI.PostSandboxByIdExec(context.Background()).Execute()
if err != nil {
return err
}use hanzo_cloud::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_exec(&cfg, Default::default()).await?;import ai.hanzo.cloud.ApiClient;
import ai.hanzo.cloud.api.SandboxApi;
ApiClient client = new ApiClient();
client.setRequestInterceptor(b -> b.header("Authorization", "Bearer " + System.getenv("HANZO_API_KEY")));
var result = new SandboxApi(client).postSandboxByIdExec();The method above is the one at the current release of the document. [email protected] (npm) and [email protected] (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.
