The auth layer
for AI agents.

Let your AI agents securely access any API — Alter Vault handles OAuth tokens, API keys, fine-grained policies, and audit logging so you don't have to.

How it works

Alter authenticates, authorizes, and logs every request

One SDK call replaces weeks of auth infrastructure. Works with every major agent framework and 100+ providers.

See it in action

Your agent asks. Alter decides.

Define what each agent can and can't do. Alter enforces it on every request, automatically.

Inside the vault

From identity to audit trail

Enterprise-grade security from day one. Every component is auditable and configurable.

Every request, fully attributed

Before anything happens, the vault resolves the full chain — organization, app, user, and actor. Every API call is traceable back to a real human, even when an AI agent makes it.

Complete chain of custody for every API call.

Organization, app, end user, and agent identified on every request
Know which agent is acting on behalf of which end user
Register each agent once — track individual runs automatically
Full delegation chain — trace any action back to its source

Tools & interfaces

Built for developers and end users

Everything developers need to ship integrations — an embeddable OAuth widget, dual SDKs,
a developer dashboard, plus a portal where end users manage their own connections.

Agents call APIs through the vault

When an AI agent needs to call an external API, it sends the request through Alter Vault — specifying the connection and the scope it needs.

Python & TypeScript parity — zero token exposure.

One line of code — specify the connection and scope
Python and TypeScript SDKs with identical interfaces
SDK handles signing automatically
