ANTHROPIC_BASE_URL/ANTHROPIC_API_KEY is not currently supported. Our organization requires routing LLM queries through a llm specific proxy for tracking and monitoring purposes. Can we support this config and skip the login in the cases where its set?

It seems like theres already a way to do this with Vertex and Bedrock, would be nice to do this natively for the claude api.

Yes it is supported

I don't think it overrides then?

docker run --rm -it node bash
npm install -g @anthropic-ai/claude-code

ANTHROPIC_BASE_URL=https://proxy.somesite.com ANTHROPIC_API_KEY=test-key claude

(note works the same using env command)

and I get:

Try HTTPS_PROXY?

@bcherny this seems like a bug though? Why not support the ANTHROPIC_API_KEY? HTTPS_PROXY wouldn't fix that. I get the urge to keep the issue system clean, but discarding legitimate issues doesn't seem like the way...

All good looks like there's a similar issue here: https://github.com/anthropics/claude-code/issues/551

Will track that one.
