## Important Notes

{% hint style="warning" %}
**Deletion is permanent:**

When you delete an instance, all associated data is **permanently deleted** and cannot be recovered. Make sure you have backed up any necessary data before proceeding.
{% endhint %}

{% hint style="warning" %}
**BYOK — Invalid API key:**

If a BYOK API key expires or is revoked after deployment, the instance will no longer be able to call the AI model. Update the key at **Settings → Config** in the OpenClaw Gateway.
{% endhint %}

If you encounter any difficulties, please contact the GreenNode team for support.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.vngcloud.vn/vng-cloud-document/ai-stack/agent-base/agent-runtime/openclaw/limitations-and-notes.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
