Auth314Verification infrastructure for Pi Sign-in

Add "verify with Pi" to your bot, app, or website without building a Pi OAuth integration yourself.

One API call

POST /verify/init and get a link back. Auth314 handles the Pi OAuth flow end to end.

Per Pi's Developer Terms of Use, a user's Pi UID and username never reach your webhook. Only a verified signal does.

A Pi account can only be linked to one platform identity at a time. Re-verifying elsewhere automatically revokes the old link.
