# deepseek-proxy

`deepseek-proxy` is published on npm as `@sunflower0305/deepseek-proxy`. It is a lightweight Express proxy that lets Claude Code or the DeepSeek Agent SDK talk to domestic Chinese LLM providers through Anthropic-compatible `/v1/messages` endpoints.

It currently supports `qwen`, `deepseek`, `glm`, `minimax`, and `kimi`.

## Install

Run without installing:

```bash
npx @sunflower0305/deepseek-proxy
```

Or install globally:

```bash
npm install -g @sunflower0305/deepseek-proxy
deepseek-proxy
```

## Configure

The proxy reads configuration from environment variables. You can export them in your shell or create a `.env` file in the directory where you run `deepseek-proxy`.

Example `.env`:

```dotenv
PROVIDER=qwen
PROXY_PORT=8080
QWEN_API_KEY=your-qwen-api-key
QWEN_MODEL=qwen-plus
```

Available variables:

| Variable | Purpose |
| --- | --- |
| `PROVIDER` | Active provider. Defaults to `qwen`. |
| `PROXY_PORT` | Local server port. Defaults to `8080`. |
| `QWEN_API_KEY` | API key for Qwen. |
| `DEEPSEEK_API_KEY` | API key for DeepSeek. |
| `GLM_API_KEY` | API key for GLM. |
| `MINIMAX_API_KEY` | API key for MiniMax. |
| `KIMI_API_KEY` | API key for Kimi. |
| `QWEN_ANTHROPIC_BASE_URL`, `DEEPSEEK_ANTHROPIC_BASE_URL`, `GLM_ANTHROPIC_BASE_URL`, `MINIMAX_ANTHROPIC_BASE_URL`, `KIMI_ANTHROPIC_BASE_URL` | Override the upstream Anthropic-compatible base URL for a provider. |
| `QWEN_MODEL`, `DEEPSEEK_MODEL`, `GLM_MODEL`, `MINIMAX_MODEL`, `KIMI_MODEL` | Override the default upstream model for a provider. |

You can use the bundled example as a starting point:

```bash
cp node_modules/@sunflower0305/deepseek-proxy/.env.example .env
```

If you installed globally, create `.env` manually or export the variables in your shell before starting the proxy.

## Start The Proxy

```bash
deepseek-proxy
```

When the server starts, it listens on `http://localhost:8080` by default.

Point Claude Code or the DeepSeek Agent SDK at the proxy:

```bash
export ANTHROPIC_BASE_URL=http://localhost:80
