configuration information, you can access the

<a href=https://www.kiali.io/api>Kiali Public API</a>.
|

For example, point your browser to <code>$KIALI_URL/api/namespaces/graph?namespaces=bookinfo&graphType=app</code>

to get the JSON representation of your graph using the <code>app</code> graph type.</p><p>The Kiali Public API is built on top of Prometheus queries and depends on the

|
standard Istio metric configuration. It also makes Kubernetes API calls to
|
|
obtain additional details about your services. For the best experience using
|
|
Kiali, use the metadata labels <code>app</code> and <code>version</code> on your application

components. As a template, the Bookinfo sample application follows this
