Is it possible to connect to AWS Bedrock API on the free plan?

I’m trying to use Claude Sonnet by connecting to the AWS Bedrock API from a cursor.
It works fine on the Pro plan, but when I try with a free plan account, I get the following message:

“The model anthropic.claude-3-5-sonnet-20240620-v1:0 does not work with your current plan or API key.”

The permissions for the IAM user are as follows: {
“Version”: “2012-10-17”,
“Statement”: [
{
“Sid”: “BedrockInvokeMinimal”,
“Effect”: “Allow”,
“Action”: [
“bedrock:InvokeModel”,
“bedrock:InvokeModelWithResponseStream”,
“bedrock:ListFoundationModels”
],
“Resource”: “*”
}
]
}

I’m wondering if this feature isn’t supported on the free plan or if it’s an API key issue.
