Why use Vercel Connect with Hail?

  • Credentials on demand

    Request Hail credentials only when your application or agent needs them instead of copying secrets into application code.

  • Access for the right subject

    Support both user-authorized and app-scoped Hail access from the same connection layer.

  • Centralized credential management

    Manage Hail credentials in one place and retrieve them through a consistent runtime API.

  • Vercel-native controls

    Bind connections to the projects and environments that need them while Vercel OIDC authenticates each runtime request.

Use Hail with your stack

Follow a complete setup for the Connect SDK or a supported agent framework.

Add Hail to an existing Vercel application with the Connect SDK.

  1. Install the Connect SDK

    npm install @vercel/connect

  2. Create the Hail connector

    Run these commands from the project that will use the connection.

    vercel link
    vercel connect create hail --name acme-hail
    vercel env pull

  3. Request Hail credentials

    app/api/route.ts
    import { getToken } from '@vercel/connect';
    

    const userId = 'user_123';
    

    const token = await getToken('hail/acme-hail', {
      subject: { type: 'user', id: userId },
