I use WKD with my gpg key tool. its quite nice!
Hmm it should be on wkd.. though the webserver might be borked.. lemme check
looks like i might be missing a policy file.. though the key is GET able.

via keyoxide with wkd: https://keyoxide.org/wkd/me%40sour.is
did some debugging and it looks like the advanced URL was breaking. @fastidious@arrakis.netbros.com @movq@www.uninformativ.de can you try the wkd now?
Odd.
