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 = "Iron Harvest 1920+ Wikipedia [PL]",
   title = "Usonia --- Iron Harvest 1920+ Wikipedia [PL]{,} ",
   year = "2025",
   url = "\url{https://pl.ironharvest.wiki/index.php?title=Usonia&oldid=221}",
   note = "[Online; accessed 3-październik-2026]"
 }
