When using the LaTeX package url (\usepackage{url} somewhere in the preamble) which tends to give much more nicely formatted web addresses, the following may be preferred:

 @misc{ wiki:xxx,
   author = "Escher Internal Wiki",
   title = "Groundhog --- Escher Internal Wiki{,} ",
   year = "2018",
   url = "\url{https://escher.icc.coop/index.php?title=Groundhog&oldid=537}",
   note = "[Online; accessed 24-April-2025]"
 }
