It reports 401 in claude - Claude Code

Quick fix

Turn the cc-switch local proxy on to convert the API format, and make sure ANTHROPIC_BASE_URL is injected into the Claude Code process.

It reports 401 in claude

Cause

Section titled “Cause”

Configuring an older OpenAI format (DeepSeek-v3, say) and having the cc-switch test pass while Claude Code errors usually means the environment variables did not reach the Claude Code process. Some users also mistake the cc-switch "proxy" for a VPN — that local proxy feature converts an OpenAI-format endpoint into the Anthropic format. Without the local proxy on, or with `ANTHROPIC_BASE_URL` misconfigured, Claude Code cannot recognise the model or returns 401.

Fix

Section titled “Fix”

  1. Confirm the local proxy is on in cc-switch settings with 接管 Claude (take over Claude) ticked.

  2. If it still does not work when launched from the cc-switch built-in terminal, set `ANTHROPIC_BASE_URL` to the proxy address by hand in a system terminal.

    ~/.zshrc 或 ~/.bash_profile
    export ANTHROPIC_BASE_URL="http://127.0.0.1:代理端口"

  3. Restart the terminal so the environment variable applies.

FAQ

Section titled “FAQ”
Which proxy do I need to turn on?
There is a local proxy switch in settings, used to convert an OpenAI-format endpoint into the Anthropic format — not a VPN.
Reaching the DeepSeek API with `http_proxy` set breaks the stream often. What now?
Configure the system proxy by default, then add a proxy bypass for deepseek in your proxy software.
Cache hit rates are low using Codex with the DeepSeek API. Is my config wrong?
That should be a deepseek problem, not a cc-switch problem.
