Artwork image in radio app

I would like show Artwork picture on my radio app. But where I found metadata link, which contains an Artwork image? Icecast server show only song title, but not Artwork.

You need to fetch the track ID from the API https://radio.org/api/live-info.

You will then receive a JSON response, in that JSON response, you should find the track ID: .current.metadata.id. (There is also a artwork_url field, but it is unusable out of the box).

With that ID you can then get the artwork if there is one using the following URL:
https://radio.org/api/track?id=<YOUR_TRACK_ID>&return=artwork
