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 = "Wikipedia",
   title = "NGC 4781 --- Wikipedia{,} Entziklopedia askea",
   year = "2020",
   url = "\url{https://eu.wikipedia.org/w/index.php?title=NGC_4781&oldid=8123640}",
   note = "[Online; accessed 11-urtarrila-2025]"
