Should be straight forward to add now that we have those examples available already. I think they are already added to the interface overview, so this should be a simple copy-paste.

Do you mean component interface examples like in the screenshot below:

Then indeed, the example can be accessed through json_kind_example property on the ComponentInterface model without the need to copy-paste them. Extra examples can be added from admin and they will override the default example.

We can also include it as a modal button instead of the download as it appears now in the component interface list view.

I'd initially suggest do add it as a plain download link to the help text.
