Could not find any example to use bedrock converse API with AnthropicBedrock

[mohitsophos]

As documented here: https://docs.anthropic.com/en/api/claude-on-amazon-bedrock#making-requests,
The following internally calls the AWS bedrock invoke API (https://docs.aws.amazon.com/bedrock/latest/userguide/bedrock-runtime_example_bedrock-runtime_InvokeModel_AnthropicClaude_section.html)

AWS also supports the converse API: https://docs.aws.amazon.com/bedrock/latest/userguide/bedrock-runtime_example_bedrock-runtime_Converse_AnthropicClaude_section.html

I tried going through repo to find an example as well but couldn't. Is this supported?

from anthropic import AnthropicBedrock

client = AnthropicBedrock(
    # Authenticate by either providing the keys below or use the default AWS credential providers, such as
    # using ~/.aws/credentials or the "AWS_SECRET_ACCESS_KEY" and "AWS_ACCESS_KEY_ID" environment variables.
    aws_access_key="<access key>",
    aws_secret_key="<secret key>",
    # Temporary credentials can be used with aws_session_token.
    # Read more at https://docs.aws.amazon.com/IAM/latest/UserGuide/id_credentials_temp.html.
    aws_session_token="<session_token>",
    # aws_region changes the aws region to which the request is made. By default, we read AWS_REGION,
    # and if that's not present, we default to us-east-1. Note that we do not read ~/.aws/config for the region.
    aws_region="us-west-2",
)

message = client.messages.create(
    model="anthropic.claude-3-5-sonnet-20241022-v2:0",
    max_tokens=256,
    messages=[{"role": "user", "content": "Hello, world"}]
)
print(message.content)

hey @mohitsophos looking at the Anthropic Bedrock client I can't see the Converse (Sream) Request URLs. Also there's no tests relating to those runtimes.

Not an official answer, but I'd say it's not supported. You'd be better off using Boto3 for now until these runtimes are added.
