No content on this site should be a web-page.
(Except, by reduction, this one.)

This small website exists for OpenPGP Web Key Directory (aka WKD).

Given the email address example@nats.io, this site allows this next command to work:
gpg --locate-external-keys example@nats.io

WKD is also used by some graphical applications, and some web-based applications; appropriate URLs should have CORS rules permitting full read access.
