# Anthropic

> Integrate with Anthropic as an AI Provider

Add your Anthropic API key to begin using Claude models in the platform—including the prompt playground, LLM-as-a-judge evaluations, and (on Enterprise) [managed agents](/docs/ax/agents/connect-your-harness#the-harness).

<Note>
  By adding this integration, your data may be sent to Anthropic for certain actions within Arize AX (e.g., prompt playground, managed agents) and your account may be billed for usage.
</Note>

## Add the Integration Using the Arize Skills

Add an Anthropic integration from your coding agent using the [Arize Skills](/docs/ax/set-up-with-ai-assistants):

<Prompt description="Create an Anthropic integration named 'my-anthropic' with my API key sk-ant...">
  Create an Anthropic integration named 'my-anthropic' with my API key sk-ant...
</Prompt>

## Add the Integration from Arize AX

### Select Anthropic from the Providers List

Give your integration a name and set your Anthropic API key.

You can find your API key in the [Anthropic Claude Console](https://platform.claude.com/settings/keys) under **API Keys**.

### Advanced Settings

</Frame>

Expand the **Advanced Settings** section to configure the following:

* **Supports Function Calling** - Turn this on to allow the integration to use function calling features. This is on by default.
* **Authorized Orgs** - Configure which organizations have access to this integration.
* **Authorized Spaces** - Configure which spaces have access to this integration.

## Add the Integration

Finally check the box to agree to the terms and conditions, then select the **Add Integration** button to create the integration.

## Use with managed agents

On Enterprise, Claude Code in managed agents can run on your Anthropic key instead of the Arize-managed default.

<Steps>
  <Step title="Create the Anthropic integration">
    Add the provider as above. Creating AI Providers requires Organization Admin or Account Admin access.
  </Step>

  <Step title="Allow use in agents">
    Enable **Allow use in agents** on the integration, or add it from **More → Agent Integrations** (**Add Agent Integration**), which opts the key into agent use automatically.
  </Step>

  <Step title="Select the integration">
    Choose it on an [agent preset](/docs/ax/agents/build-your-own-agent), in [Agent Studio](/docs/ax/agents/build-your-own-agent), when enabling [Signal](/docs/ax/observe/signal), or as the space default under **Space Settings**.
  </Step>
</Steps>

Enterprises that must not use Arize-managed models can request that Arize disable the Arize-managed integration—contact your Arize account team.
