A user reported needing to customize the Bedrock endpoint to relay requests through an internal proxy which ultimately relays requests to Bedrock.

They are currently using Claude Code to interact with this proxy by using the following env vars:

• CLAUDE_CODE_USE_BEDROCK=1
• CLAUDE_CODE_SKIP_BEDROCK_AUTH=1
• ANTHROPIC_BEDROCK_BASE_URL=corp.proxy

Additionally they need to be able to set static HTTP headers to go along with each request. See #135.
