Claude Code API Key via Third Party

Claude API Key can be provided by a third party.

Third parties include:

Amazon Bedrock
Google Vertex AI
Microsoft Foundry

Generally the way it works is you authenticate with your provider, maybe provide an additional key, then set an env var flag to tell Claude to use that specific provider:

export AWS_BEARER_TOKEN_BEDROCK=your-bedrock-api-key
export CLAUDE_CODE_USE_BEDROCK=1
