# Volcengine (Doubao)

The Volcengine provider gives access to Doubao models and third-party models
hosted on Volcano Engine, with separate endpoints for general and coding
workloads.

| Detail    | Value                                               |
| --------- | --------------------------------------------------- |
| Providers | `volcengine` (general) + `volcengine-plan` (coding) |
| Auth      | `VOLCANO_ENGINE_API_KEY`                            |
| API       | OpenAI-compatible                                   |

## Getting started

<Steps>
  <Step title="Set the API key">
    Run interactive onboarding:

    ```bash
    openclaw onboard --auth-choice volcengine-api-key
    ```

    This registers both the general (`volcengine`) and coding (`volcengine-plan`) providers from a single API key.

  </Step>
  <Step title="Set a default model">
    ```json5
    {
      agents: {
        defaults: {
          model: { primary: "volcengine-plan/ark-code-latest" },
        },
      },
    }
    ```
  </Step>
  <Step title="Verify the model is available">
    ```bash
    openclaw models list --provider volcengine
    openclaw models list --provider volcengine-plan
    ```
  </Step>
</Steps>

<Tip>
For non-interactive setup (CI, scripting), pass the key directly:

```bash
openclaw onboard --non-interactive \
  --mode local \
  --auth-choice volcengine-api-key \
  --volcengine-api-key "$VOLCANO_ENGINE_API_KEY"
```

</Tip>

## Providers and endpoints

| Provider          | Endpoint                                  | Use case       |
| ----------------- | ----------------------------------------- | -------------- |
| `volcengine`      | `ark.cn-beijing.volces.com/api/v3`        | General models |
| `volcengine-plan` | `ark.cn-beijing.volces.com/api/coding/v3` | Coding models  |

<Note>
Both providers are configured from a single API key. Setup registers both automatically.

## Advanced notes

<AccordionGroup>
  <Accordion title="Default model after onboarding">
    `openclaw onboard --auth-choice volcengine-api-key` currently sets
    `volcengine-plan/ark-code-latest` as the default model while also registering
    the general `volcengine` catalog.
  </Accordion>

  <Accordion title="Model picker fallback behavior">
    During onboarding/configure model selection, the Volcengine auth choice prefers
    both `volcengine/*` and `volcengine-plan/*` rows. If those models are not
    loaded yet, OpenClaw falls back to the unfiltered catalog instead of showing an
    empty provider-scoped picker.
  </Accordion>

  <Accordion title="Environment variables for daemon processes">
    If the Gateway runs as a daemon (launchd/systemd), make sure
    `VOLCANO_ENGINE_API_KEY` is available to that process (for example, in
    `~/.openclaw/.env` or via `env.shellEnv`).
  </Accordion>
</AccordionGroup>

<Warning>
When running OpenClaw as a background service, environment variables set in your
interactive shell are not automatically inherited. See the daemon note above.
</Warning>
