# Anthropic SDK (/zh-Hant/docs/guides/anthropic-sdk)

搭配 cheapaimodel 使用官方 Anthropic Python 與 TypeScript SDK。



<Callout type="warn">
  **尚無法使用。** [目錄](/zh-Hant/models)中目前沒有任何模型列有 Anthropic Messages 端點（`/v1/messages`）。請先改用 [OpenAI SDK](/zh-Hant/docs/guides/openai-sdk)。等到有模型的目錄頁列出 `/v1/messages`，本指南即適用。
</Callout>

Anthropic SDK 呼叫的是 `/v1/messages`。設定 Base URL 時**不要**加上 `/v1`，SDK 會自行補上路徑。

```bash title="終端機"
export ANTHROPIC_BASE_URL="https://api.cheapaimodel.ai"

請把 `<model-id>` 換成[目錄](/zh-Hant/models)中列有 `/v1/messages` 的模型。
