How do I find my Halo Security API Key?

Log in to your Halo Security account, navigate to **Account Settings** and then to the **API** section. You will be able to generate and copy your unique API key from there.

Can I trigger a new scan through this integration?

Yes! Use the `trigger_scan` tool by providing the unique target ID of the asset you want to assess. Halo Security will initiate the scan immediately.

How are security issues categorized?

Issues are categorized by their severity (e.g., Critical, High, Medium, Low) and type (e.g., Vulnerability, Information, SSL Issue). You can use `list_issues` to see all findings.

Is it possible to add new domains to monitor?

Yes, the `add_target` tool allows you to add new domains or IP addresses to your security perimeter directly from the AI agent.
