How to Use Anthropic’s Claude Platform Directly from Your AWS Account

Claude Platform on AWS

Claude Platform is available on Amazon Web Services, allowing enterprise developers to use Anthropic’s native Claude Platform API and features with an existing AWS account, without separate account registration, credential management, contracts, or billing.

Key capabilities

The AWS‑hosted service provides the same API, console experience, and features as the Anthropic native platform, including Messages API, Claude‑hosted Agents (beta), Advisor tools (beta), web search and web scraping, MCP connector (beta), Agent Skills (beta), code execution, and file API (beta). The complete feature list is documented in the Claude Platform official documentation.

Authentication, billing, and auditing

Identity authentication : Use existing Amazon IAM credentials to access Claude Platform; no extra accounts or API keys are required.

Billing : Usage is billed through the AWS Marketplace on a pay‑as‑you‑go basis, enabling unified cost tracking and management.

Audit logs : All actions are recorded by Amazon CloudTrail, supporting standard monitoring, auditing, and investigation of AI calls.

Getting started

Step 1 – Create a workspace

Workspaces isolate projects, environments, or teams while keeping unified billing and management. Access to a workspace is controlled via IAM policies that reference the workspace ARN (see the IAM policy example).

Step 2 – Authenticate

Claude Platform on AWS supports two authentication methods: IAM‑based Signature V4 and API‑key authentication. Temporary IAM credentials provide higher security; API‑key authentication is convenient for quick trials. An API key can be generated directly in the Claude Platform console.

Step 3 – Make the first API call

Set the required environment variables:

# Your API key
export ANTHROPIC_API_KEY=<YOUR API KEY HERE>

# Regional endpoint for Claude Platform on AWS
export ANTHROPIC_BASE_URL=https://aws-external-anthropic.<YOUR REGION HERE>.api.aws

# Workspace ID (found in the console → Workspaces)
export ANTHROPIC_WORKSPACE_ID=<YOUR WORKSPACE ID HERE>

Python example using the Anthropic SDK:

from anthropic import Anthropic
import os

client = Anthropic(
    default_headers={"anthropic-workspace-id": os.environ["ANTHROPIC_WORKSPACE_ID"]},
)

message = client.messages.create(
    model="claude-sonnet-4-6",
    max_tokens=1024,
    messages=[{"role": "user", "content": "Hello!"}],
)
print(message)

Monitoring, logging, and cost management

All calls made via the Anthropic SDK, Claude Code, or Claude Cowork are recorded by Amazon CloudTrail. Workspace‑related operations appear as management events; data‑event logging can be enabled to capture model‑inference calls. Since usage is billed through the AWS Marketplace, costs can be tracked in Amazon Cost Explorer and allocated with resource tags.

Regional availability

The service is available in the following AWS regions: US East (N. Virginia, Ohio), US West (Oregon), Canada (Central), South America (São Paulo), Europe (Dublin, London, Frankfurt, Milan, Zurich, Paris, Stockholm), and APAC (Tokyo, Seoul, Jakarta, Sydney, Melbourne).
