code_execution: run sandboxed remote Python analysis with xAI	You want to enable or configure code_execution You want remote analysis without local shell access You want to combine x_search or web_search with remote Python analysis	Code execution

code_execution runs sandboxed remote Python analysis on xAI's Responses API (https://api.x.ai/v1/responses, same endpoint x_search uses). It is registered by the bundled xai plugin under the tools contract.

`code_execution` runs on xAI's servers. xAI bills $5 per 1,000 tool calls, plus the model's input and output tokens.

Property	Value
Tool name	code_execution
Provider plugin	xai (bundled, enabledByDefault: true)
Auth	xAI auth profile, XAI_API_KEY, or plugins.entries.xai.config.webSearch.apiKey
Default model	grok-4.3
Default timeout	30 seconds
Default maxTurns	unset (xAI applies its own internal limit)

Use it for calculations, tabulation, quick statistics, and chart-style analysis, including data returned by x_search or web_search. It has no access to local files, your shell, your repo, or paired devices, and it does not persist state between calls, so treat each call as ephemeral analysis, not a notebook session. For fresh X data, run x_search first and pipe the result in.

For local execution, use exec instead.

Setup

OAuth requires an eligible SuperGrok or X Premium subscription (device-code verification, so it works from remote hosts without a localhost callback):

```bash
openclaw models auth login --provider xai --method oauth
```

During a fresh install, the same choice is available in onboarding:

```bash
openclaw onboard --install-daemon --auth-choice xai-oauth
```

Or an API key:

```bash
openclaw models auth login --provider xai --method api-key
export XAI_API_KEY=xai-...
```

Or via config:

```json5
{
  plugins: {
    entries: {
      xai: {
        config: {
          webSearch: {
            apiKey: "xai-...",
          },
        },
      },
    },
  },
}
```

Any of these three also power `x_search` and Grok `web_search`.

With `enabled` omitted, `code_execution` is exposed only when the active model's provider is `xai` and xAI credentials resolve. For an active model with a known non-xAI provider, set `plugins.entries.xai.config.codeExecution.enabled` to `true` to opt in to cross-provider use. If the active model provider is missing or unresolved, the tool stays hidden. Set `enabled` to `false` to disable it for every provider. xAI credentials are always required.

Use the same block to override the model, turn cap, or timeout:

```json5
{
  plugins: {
    entries: {
      xai: {
        config: {
          codeExecution: {
            enabled: true, // required for a known non-xAI model provider
            model: "grok-4.3", // override the default xAI code-execution model
            maxTurns: 2,            // optional cap on internal tool turns
            timeoutSeconds: 30,     // request timeout (default: 30)
          },
        },
      },
    },
  },
}
```

```bash openclaw gateway restart ```

`code_execution` appears in the agent's tool list once the xAI plugin
re-registers and the provider, enablement, and auth checks above pass.

How to use it

Make the analysis intent explicit; the tool takes a single task parameter, so send the full request and any inline data in one prompt:

Use code_execution to calculate the 7-day moving average for these numbers: ...

Use x_search to find posts mentioning OpenClaw this week, then use code_execution to count them by day.

Use web_search to gather the latest AI benchmark numbers, then use code_execution to compare percent changes.

Errors

Without auth, the tool returns a structured JSON error (not a thrown exception), so the agent can self-correct:

{
  "error": "missing_xai_api_key",
  "message": "code_execution needs xAI credentials. Run `openclaw onboard --auth-choice xai-oauth` to sign in with Grok, run `openclaw onboard --auth-choice xai-api-key`, set `XAI_API_KEY` in the Gateway environment, or configure `plugins.entries.xai.config.webSearch.apiKey`.",
