Comment on How To Parse JSON Data To A Human Readable Format

Since you are using n8n, pull the data on a schedule and save it in a data table. Then create a webhook to serve the content as you want it. N8n can transform the JSON data, I can provide a sample tomorrow.
That would be swell, but I wouldn’t make it a priority. Just whenever you get a round to it. I have been given a ton of source material to read. Stayed up a little too late last night trying to assimilate it all. LOL

Sharing a workflow requires a paid plan but could should be able to paste this in the editor to get the same effect.
I made two different sample flows, on that call the api and responds with directly with the response data (transformed). The other workflow is to same the data in a data table, and call the weather api on a schedule. You could even use ntfy and send notifications on a schedule if it will rain within an hour.
Edit the nodes to suite your need (URL, content of response etc).
n8n sample workflow (copy and paste in n8n's editor)

I’m doing a bit of tweaking but it certainly jump started the process. You’re a scholar and a gentleman.

Glad to hear that you got it working! The hard part for me was to figure out how to transform a JSON string into an array of n8n objects. I had already done that before so now I just copy that node whenever I need something like again.
I figured you would have. But that is half the fun. :-)
Oh Snap! You didn’t. I will definitely get this running in a bit when I finish all my chores and can go play. Wow man, thank you so much!! I had put this on my dashboard as a means of encouragement to finish what I started.
