AWS Bedrock

Provider value: bedrock

Setup

Option 1: AWS credential chain (recommended)

ra uses the standard AWS credential chain:

1. AWS_ACCESS_KEY_ID / AWS_SECRET_ACCESS_KEY env vars
2. ~/.aws/credentials file
3. IAM instance roles

export AWS_ACCESS_KEY_ID=...
export AWS_SECRET_ACCESS_KEY=...
export AWS_REGION=us-east-1
ra --provider bedrock "Hello"

Option 2: Bearer token

A bearer token can be set in a config file:

app:
  providers:
    bedrock:
      apiKey: your-bearer-token

export AWS_REGION=us-east-1
ra --provider bedrock "Hello"

Custom endpoint

Use baseURL to point at a custom or proxy endpoint (e.g. a VPC endpoint, LocalStack, or a Bedrock-compatible gateway):

app:
  providers:
    bedrock:
      baseURL: https://vpce-abc123.bedrock-runtime.us-east-1.vpce.amazonaws.com

Or via CLI flag:

ra --provider bedrock --bedrock-base-url https://vpce-abc123.bedrock-runtime.us-east-1.vpce.amazonaws.com "Hello"

Variable	Required	Description
