为 Python、Node.js、curl、Cursor、LiteLLM、FastGPT、Codex 风格工具，以及 Crazyrouter 全球或区域端点生成清晰的 Base URL 配置片段。
OpenAI-compatible SDKs usually need the Base URL to include /v1. Use https://crazyrouter.com/v1, not just the domain.
If you use the Crazyrouter Base URL, use a Crazyrouter API key from your dashboard, not a provider-native key.
If global access is unstable, switch only the Base URL to https://cn.crazyrouter.com/v1. Keep the same API key and model name.
