Claude Code

Claude Code uses /anthropic, not /v1.

Claude Code is Anthropic-native. The safest first setup is the Anthropic base URL, your CorvusLLM key as ANTHROPIC_AUTH_TOKEN, and the clean starter slug claude-opus-4-7.

PowerShell

PowerShell
$env:ANTHROPIC_BASE_URL="https://base.corvusllm.com/anthropic"
$env:ANTHROPIC_AUTH_TOKEN="YOUR_CORVUSLLM_KEY"
$env:ANTHROPIC_MODEL="claude-opus-4-7"
claude

macOS / Linux

bash/zsh
export ANTHROPIC_BASE_URL="https://base.corvusllm.com/anthropic"
export ANTHROPIC_AUTH_TOKEN="YOUR_CORVUSLLM_KEY"
export ANTHROPIC_MODEL="claude-opus-4-7"
claude

Why this page is different from the /v1 pages

Claude Code does not want the OpenAI-compatible base URL. It wants an Anthropic-style gateway and will then call the Anthropic-native message endpoints under the hood.

Best first model

Start with claude-opus-4-7. After the first successful request, you can switch to other Claude slugs from Models & Slugs.
