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.

Install Claude Code first

Claude Code is a local CLI. Install Node.js if npm is missing, install Claude Code from Anthropic, then set the CorvusLLM Anthropic base URL and key from the next sections.

Configure

Set the Anthropic environment variables in the same terminal session that will run claude.

  • Set ANTHROPIC_BASE_URL to https://base.corvusllm.com/anthropic
  • Set ANTHROPIC_AUTH_TOKEN to your delivered CorvusLLM key
  • Set ANTHROPIC_MODEL to claude-opus-4-7
3
Verify
  • Run claude from the same terminal after setting variables
  • Ask for one short answer before letting it edit a real project

Claude Code opens from the configured terminal and answers one short prompt before project edits are attempted.

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.
