44description: Access Claude models through Amazon Bedrock with AWS-native authentication, billing, and security boundaries.
55---

7This guide walks you through setting up and making API calls to Claude in Amazon Bedrock. Claude in Amazon Bedrock runs on AWS-managed infrastructure with zero operator access (Anthropic personnel have no access to the inference infrastructure), letting you build sensitive applications entirely inside the AWS security boundary while using the same Messages API shape you use with Anthropic's first-party API.

1010 This page covers Claude in Amazon Bedrock, which serves Claude through the Messages API at `/anthropic/v1/messages` on AWS-managed infrastructure. The previous Amazon Bedrock integration (the `InvokeModel` and `Converse` APIs with ARN-versioned model identifiers) remains available and is documented at [Claude on Amazon Bedrock (Opus 4.6 and earlier)](https://platform.claude.com/docs/en/build-with-claude/claude-on-amazon-bedrock-legacy). For an Anthropic-operated alternative on AWS with AWS Marketplace billing and typically same-day feature access, see [Claude Platform on AWS](https://platform.claude.com/docs/en/build-with-claude/claude-platform-on-aws).

15Amazon Bedrock sets access criteria for each Claude model individually. Claude Fable 5.1, Claude Fable 5, Claude Opus 4.8, Claude Sonnet 5, Claude Opus 4.7, and Claude Haiku 4.5 are open to all Amazon Bedrock customers. For any other model's current criteria, check [Amazon Bedrock model access](https://console.aws.amazon.com/bedrock/home#/modelaccess) in the AWS console. Claude Mythos Preview requires an invitation through [Project Glasswing](https://anthropic.com/glasswing). For region availability, see [Regions](https://platform.claude.com/docs/en/build-with-claude/claude-in-amazon-bedrock#regions).

2121* An AWS account with [Amazon Bedrock model access](https://console.aws.amazon.com/bedrock/home#/modelaccess) enabled for the Claude models you intend to use
2222* The [AWS CLI](https://docs.aws.amazon.com/cli/latest/userguide/getting-started-install.html) installed and configured (optional, for credential management)

24Claude Mythos Preview additionally requires a dedicated AWS account that has been allowlisted by the Bedrock Marketplace team. Your Anthropic account executive can submit your account ID for allowlisting (typically processed within 24 hours), and AWS sends a welcome email once it's complete.

144The endpoint follows the pattern `https://bedrock-mantle.{region}.api.aws/anthropic/v1/messages`. Unlike the `InvokeModel`-based integration, this endpoint uses standard SSE streaming and the same request body shape as Anthropic's first-party API.

146146The SDK resolves credentials and region using the standard AWS precedence: constructor arguments, then environment variables (`AWS_ACCESS_KEY_ID`, `AWS_SECRET_ACCESS_KEY`, `AWS_SESSION_TOKEN`, `AWS_REGION`), then the AWS config file and credential chain (SSO, assumed roles, ECS task role, IMDS).
