AwsBackend

All Implemented Interfaces:

com.anthropic.backends.Backend
```
public final class AwsBackend
 implements Backend
                    
```
The AWS backend that manages the AWS credentials or API key required to access Anthropic's AI models via the AWS API gateway and signs requests using AWS SigV4.
Unless using an API key, requests are cryptographically signed using credentials issued by AWS. These can be provided via system properties, environment variables, or other AWS facilities. They can be resolved automatically by the default AWS provider chain by calling Builder.fromEnv. Alternatively, a custom AWS credentials provider can be configured on the builder.
If using an API key, the key can be set directly, or provided via the ANTHROPIC_AWS_API_KEY environment variable. If that variable is set, it will be resolved by Builder.fromEnv unless an AWS credentials provider is specified explicitly to that method.
Both the credentials (or API key) and the region can be resolved independently and passed to Builder.awsCredentials (or Builder.apiKey) and Builder.region should an alternative method of resolution be required.
A workspace ID must be set via Builder.workspaceId or the ANTHROPIC_AWS_WORKSPACE_ID environment variable. It is sent as the anthropic-workspace-id request header.
See the AWS documentation for details on how to configure AWS credentials.

Nested Class Summary

Nested Classes
Modifier and Type	Class	Description
`public final class`	`AwsBackend.Builder`	A builder for an AwsBackend used to connect an Anthropic client to the AWS API gateway backend service. The AWS credentials and region can be extracted from the environment and set on the builder by calling fromEnv before calling build to create the AwsBackend. Alternatively, set the AWS credentials and region explicitly via awsCredentials and region before calling build. A custom AWS credentials provider can be passed to fromEnv or awsCredentialsProvider. You should set either the AWS credentials provider or the API key, but not both. If both are set, an error will occur.
