I am trying to create an autocomplete search box for a signup form, where the input will be an artist name from the Songkick.com API, but it is using Blockspring RSS to JSON in order to fetch the artists from Songkick. I am running into trouble with the dynamic options and fetching from the external API. Does anyone have experience doing this or something similar? The example RSS and JSON is shown below.
