Install an SDK

Anthropic's client SDKs support Claude Platform on AWS. Each SDK provides a platform-specific client class that handles SigV4 signing, region-based base URL construction, and the anthropic-workspace-id header.

```bash
pip install -U "anthropic[aws]"
```

  On macOS with Homebrew Python or other externally managed Python environments, `pip install` can fail with a PEP 668 `externally-managed-environment` error. Create and activate a virtual environment first: `python3 -m venv .venv && source .venv/bin/activate`.

```bash
npm install @anthropic-ai/aws-sdk
```

```bash
dotnet add package Anthropic.Aws
```

```bash
go get github.com/anthropics/anthropic-sdk-go
```

```kotlin Gradle
implementation("com.anthropic:anthropic-java-aws:2.60.0")
```

```xml Maven
<dependency>
  <groupId>com.anthropic</groupId>
  <artifactId>anthropic-java-aws</artifactId>
  <version>2.60.0</version>
</dependency>
```

```bash
composer require anthropic-ai/sdk aws/aws-sdk-php
```

```bash
gem install anthropic aws-sdk-core
```

SDK clients for Claude Platform on AWS are in beta.
