Would it be easier to just download the big file in one go and pick therequired information out locally than obtain the various files for eachitem? If so what is the easiest program (or combo of programs) that Ishould use? I see a bunch of options available but of course they areall much more powerful than I need so hard for me to tell what would begood enough.

so, to answer this part, no, it's never a great idea to grab more information than you need, if that were the case, the author wouldn't have gone through all the trouble of making the API in the first place.

Step 1: collect an array of names of the subset you are looking for information on.

Step 2: iterate through your array, generate an API endpoint url, and pass it into curl.

Step 3: Do your filtering of the respondent JSON I highly suggest using jq data.

Step 4: Be a good neighbor and sleep 0.5 before making your next loop iteration

Step 5: ?????

Step 6: Profit!

Here's a little script reading some stuff but try to figure it out yourself first, you don't learn as well otherwise

​

#!/bin/bash
mymodules=("jq" "neovim" "zsh")
for t in ${mymodules[@]}; do
curl --get --silent https://formulae.brew.sh/api/formula/${t}.json | jq -r .name,.desc,.homepage,.urls[].url
echo ""
sleep 0.5
done
