# Google Agent Platform & Gemini Enterprise

> Use StackOne A2A agents from agents built on Google's Agent Platform, and register them in Gemini Enterprise.

## Overview

StackOne A2A agents are standard [A2A](https://a2a-protocol.org/latest/) agents, so they can be called from agents built and run on [Google's Agent Platform](https://docs.cloud.google.com/gemini-enterprise-agent-platform/overview), and registered in [Gemini Enterprise](https://cloud.google.com/gemini-enterprise). The StackOne agent itself runs on Google's [Agent Development Kit (ADK)](https://google.github.io/adk-docs/), see [How StackOne A2A works](/a2a/introduction#how-stackone-a2a-works) for more.

## Google Agent Platform

Agents you build on [Google's Agent Platform](https://docs.cloud.google.com/gemini-enterprise-agent-platform/overview) can call a StackOne A2A agent as a remote A2A agent, the same pattern shown in the [ADK guide](/a2a/framework-guides/adk). Point your agent at the StackOne agent card and it can search and execute StackOne actions across your connected SaaS applications.

## Gemini Enterprise

[Gemini Enterprise](https://cloud.google.com/gemini-enterprise) and similar platforms register a static agent URL and call it on your behalf. So that this works without you handling credentials in the platform, StackOne provisions a pre-authorized agent scoped to your account, which the platform can call directly.

<Note>
  To enable StackOne A2A in Gemini Enterprise or Google's Agent Platform, contact the StackOne team at [contact@stackone.com](mailto:contact@stackone.com) and we will set up a pre-authorized agent for your account.
