webfinger

to add your own, run the webfinger tool at your shell.

it will prompt you for your fedi handle and save the correct json to ~/.webfinger.json.

you can do this manually by grabbing the webfinger from your fedi host.

as an example, to get the webfinger response for @ben@tilde.zone

curl https://tilde.zone/.well-known/webfinger?resource=acct%3Aben%40tilde.zone > ~/.webfinger.json

see webfinger.net for more info and a simple tester for your setup.
