This could be done quite easily with a html, javascript and formatting the data as a json file, the result would be almost instantaneous and you don't need to spend resources to run a bot.
I want to run it from a VPN instead of my desktop, that's why I hope to find a solution that works from the command line. Javascript sounds like it requires a browser, am I right?
If you are interested i can show how on Monday. It is a nice idea nevertheless

If it can run from the command line, I'd like to learn how.
As an alternative, I'm now considering generating full merit histories for all users weekly instead of "on demand", but I'll need bigger file hosting.
I didn't understand exactly your requirement, but basically this is what i had in mind and did in the end:
https://albertoit.github.io/Visualization/Merit%20js%20tool/filterMeritLocal.html?id=loycevI also extended also the idea a bit to allow qurying the information based on some parameter like sender, receiver, merits, date range.
Is running on github pages( it can be controlled through command line, i mean pushing the files there), istructions and details are here:
https://bitcointalk.org/index.php?topic=4456438.0Then i wanted to ask one more thing, do you happen to have a list of merit sources ready? So i spare mayself the job to make it somehow
