You need to use #renderHead() method of Component or Behavior. Read https://ci.apache.org/projects/wicket/guide/7.x/single.html#_adding_resources_to_page_header_section for more information.
public class MyComponent extends Component{
@Override
public void renderHead(IHeaderResponse response) {
String json = ...;
response.render(JavaScriptHeaderItem.forScript(json));
}
}

//We need to call a fetch function in the script tags fam
<script>
fetch('localhost:8080/getMyJson', (res, err) => {
err ? console.err(err) : console.log(res)
})
</script>
// the default HTTP method is set as GET
