@noiob maybe a loop that pings /api/v1/instance and checks to see if it returns a 200?
in bash, something like:
for site in $(cat sites); do
curl --fail $site/api/v1/instance && echo $site >> valid
done
@thingywott I mean *I* didn't write any code for that, so it's perfect :P
@noiob hee, fair enough!
