API v2 get audio files for review

[Kumirei]

You can use the Wanikani Open Framework, which caches item data, then just fetch the audio URLs from there.

wkof.include('ItemData');
wkof.ready('ItemData').then(get_items);

function get_items() {
    config = {...};
    wkof.ItemData.get_items(config).then(do_stuff);
}

function do_stuff(items) {
    // Do stuff
}
