Your keys

Vigia has no servers of its own, so it uses your credentials: always a Jev key, and a Twitch app if you want to moderate your channel.

Jev key

A Vercel AI Gateway key (it starts with vck_) or a TypeSafe key both work.

Usage is billed to your account:

• $0.042 per million input tokens.
• Output is free.
• A busy night of chat usually costs cents.

The dashboard’s Stats tab shows an hourly cost estimate.

Twitch app

You only need it for My channel. Twitch requires two-factor authentication on your account before you can register apps.

1. Open the Twitch developer console and choose Register Your Application.
2. Fill in the form:
   • Name: anything unique, for example vigia-yourname.
   • OAuth Redirect URL: http://localhost. If you use server mode, also add https://<your domain>/auth/callback.
   • Category: Chat Bot.
   • Client type: Public.
3. Create it, open Manage, and copy the Client ID. There is no secret to keep.

Signing in to Twitch

Vigia uses Twitch’s device code: it shows you a code and you confirm it on twitch.tv. It only asks for the permissions it uses:

• Reading and sending chat.
• Deleting messages, timeouts and bans.
• Seeing who your mods are.

Vigia never issues permanent bans on its own: those are always a person’s call.
