# curl (/zh-Hant/docs/guides/curl)

從命令列呼叫每個端點。



先設定一次你的 Key：

```bash title="終端機"
export CHEAPAIMODEL_API_KEY="sk-..."
```

## 列出模型 [#列出模型]

```bash
curl https://api.cheapaimodel.ai/v1/models \
  -H "Authorization: Bearer $CHEAPAIMODEL_API_KEY"
```

## Chat completion [#chat-completion]

```bash
curl https://api.cheapaimodel.ai/v1/chat/completions \
  -H "Authorization: Bearer $CHEAPAIMODEL_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"model": "deepseek-v4-1-flash", "messages": [{"role": "user", "content": "Hello!"}]}'
```

加上 `"stream": true` 並傳入 curl 的 `-N` 參數，即可在 token 送達時立即看到。
