MyJSON.com is gone...how do I get a URL to update my Roku Channel? Help!

I was told this question belongs in the Direct Publisher Forum, so hopefully someone out there can help!

--------

For the past couple years, I've used MyJSON.com to generate the JSON URL I need for updates to my Roku channel (Fore Golfers Network).

I'm a complete novice at all things JSON, learning just enough to update the full code and then grab the URL from MYJSON. That site is now dead (he closed it April 1) and I have no idea where I can go for the URL so I'm unable to update my channel w/ fresh content.
