​
Getting started

1

Set the API key

Run interactive onboarding:
openclaw onboard --auth-choice volcengine-api-key
This registers both the general (volcengine) and coding (volcengine-plan) providers from a single API key.
2

Set a default model

{
  agents: {
    defaults: {
      model: { primary: "volcengine-plan/ark-code-latest" },
    },
  },
}
3

Verify the model is available

openclaw models list --provider volcengine
openclaw models list --provider volcengine-plan
For non-interactive setup (CI, scripting), pass the key directly:
openclaw onboard --non-interactive \
  --mode local \
  --auth-choice volcengine-api-key \
  --volcengine-api-key "$VOLCANO_ENGINE_API_KEY"

Providers and endpoints

ProviderEndpointUse case
volcengineark.cn-beijing.volces.com/api/v3General models
volcengine-planark.cn-beijing.volces.com/api/coding/v3Coding models
Both providers are configured from a single API key. Setup registers both automatically.

Advanced notes

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