I played a bit with the Millenium Bible site and it seems that you are able to achieve something similar using their otworz.php API: https://biblia.deon.pl/otworz.php?skrot=Ga%204, where the skrot parameter accepts the <book>[space]<chapter> format. You can then use the anchor to link to a given verse number using the html name params W<verse>.
So a full example would be https://biblia.deon.pl/otworz.php?skrot=Ga%204#W10
