Tried it.. pretty straight forward. Free account rate is good for personal use. I think it comes down to 4 calls per day which is reasonable if you are using this as maybe your daily news fetcher.
Thanks for the feedback! Concerning rate limiting, I think I may have placed rules a bit too strict, as the system is hosted on AWS Free Tier. There is definitely a room for increase in RPS per user, but I wanted to play safe.
