# x-antigravity
OpenClaw provider plugin: Antigravity models through an AxonHub gateway (OpenAI format).
- Provider `x-antigravity/`, shown in the model picker as **X Antigravity**.
- Models: models with `owned_by: antigravity`, discovered live from AxonHub's `/v1/models`. New models appear after a Refresh in the model picker, or once the 60 s discovery cache expires.
- Embedding and other non-chat models are filtered out.
- Adding a key never replaces the primary model chosen in the UI.
## API address and key
Set them in the OpenClaw UI (**Plugins → X Antigravity → Settings**) or with env vars. The UI setting wins.
| Setting | UI field | Env var | Example |
| ------- | -------- | ------- | ------- |
| API address | `baseUrl` | `X_ANTIGRAVITY_BASE_URL` | `https://axonhub.example.com/v1` |
| API key | `apiKey` | `X_ANTIGRAVITY_API_KEY` | API key |
| Context window | `contextWindow` | `X_ANTIGRAVITY_CONTEXT_WINDOW` | optional, default: the value AxonHub reports |
| Streaming | `streaming` | `X_ANTIGRAVITY_STREAMING` | `true` (default) |
The key can also be saved as an auth profile under **Settings → Model providers**, or with `openclaw models auth paste-api-key --provider x-antigravity`. Order: UI `apiKey`, then the auth profile, then the env var.
With Docker Compose, the container only sees variables passed under `environment:`, e.g. `- X_ANTIGRAVITY_API_KEY=${X_ANTIGRAVITY_API_KEY}`.
## Install into an OpenClaw container
The plugin lives on the data volume, so it survives redeploys.
```sh
C=<openclaw container>
docker exec $C rm -rf /data/plugins/x-antigravity
docker cp . $C:/data/plugins/x-antigravity
# OpenClaw ignores plugin dirs that are not root-owned or are group-writable
docker exec $C sh -c 'rm -rf /data/plugins/x-antigravity/.git && chown -R root:root /data/plugins/x-antigravity && chmod 755 /data/plugins/x-antigravity && chmod 644 /data/plugins/x-antigravity/*'
docker exec $C openclaw plugins install --link /data/plugins/x-antigravity --force
```
## Update after editing
Run the first three commands above again, then:
```sh
docker exec $C openclaw plugins reload x-antigravity
```
