# Claude Code CLI

[← back to overview](index.md)

Claude Code speaks the **Anthropic Messages API** — point it at the gateway's unified endpoint, not llama.cpp directly:

```bash
export ANTHROPIC_BASE_URL=http://<ai-box>:${OMNIROUTE_PORT:-4000}
export ANTHROPIC_API_KEY=<claude-code-cli virtual key>
claude
```

Requires llama.cpp's `--jinja` flag (already set in `docker-compose.yml`) — without it, tool-use requests fail outright.
