But my understanding is Claude Code is closed source and only support Clade API endpoint. How do they make it work? You set the environment variable ANTHROPIC_BASE_URL to an OpenAI-compatible endpoint and ANTHROPIC_AUTH_TOKEN to the API token for the service. I used Kimi-K2 on Moonshot [1] with Claude Code with no issues. There's also Claude Code Router and similar apps for routing CC to a bunch of different models [2].
