description: 對 Claude 發出您的第一個 API 呼叫，並建構一個簡單的網頁搜尋助理。

## 先決條件

* 一個 [Claude Console 帳戶](https://platform.claude.com)
* 一組 [API 金鑰](https://platform.claude.com/docs/zh-TW/get-api-key)

## 呼叫 API

<Tabs>
  <Tab title="cURL">
    <Steps>
      <Step title="設定您的 API 金鑰">
        將您的 API 金鑰匯出為環境變數。下方的 cURL 命令會從 `$ANTHROPIC_API_KEY` 讀取它。

        ```bash
        export ANTHROPIC_API_KEY="your-api-key-here"
        ```
      </Step>

      <Step title="發出您的第一個 API 呼叫">
        向 Messages API 發送 `POST` 請求：

        ```bash cURL
        curl https://api.anthropic.com/v1/messages \
          -H "content-type: application/json" \
          -H "x-api-key: $ANTHROPIC_API_KEY" \
          -H "anthropic-version: 2023-06-01" \
          -d '{
            "model": "claude-opus-5-5",
            "max_tokens": 1000,
            "messages": [
              {
                "role": "user",
                "content": "What should I search for to find the latest developments in renewable energy?"
              }
            ]
          }'
        ```

        Claude 會回傳一個包含助理訊息的 JSON 回應：

        ```json Output
        {
          "model": "claude-opus-5-5",

        ```
      </Step>
    </Steps>
  </Tab>

  <Tab title="CLI">
    <Steps>
      <Step title="安裝 CLI">
        使用 Homebrew 安裝 Anthropic CLI：

        ```bash
        brew install anthropics/tap/ant
        ```

        如需其他安裝方式，請參閱 CLI 快速入門中的[安裝](https://platform.claude.com/docs/zh-TW/cli-sdks-libraries/cli/quickstart#installation)。
      </Step>

      <Step title="驗證身分">
        使用您的 Anthropic 帳戶登入：

        ```bash
        ant auth login
        ```

        這會開啟一個基於瀏覽器的 OAuth 流程。授權後，使用以下命令確認您的憑證：

        ```bash
        ant auth status
        ```

        在沒有瀏覽器的遠端主機上，請傳入 `--no-browser` 以取得可在其他裝置上開啟的 URL，然後將回傳的代碼貼回終端機。如果您的環境中已設定 `ANTHROPIC_API_KEY`，它會優先於登入憑證。對於 CI 等非互動式環境，請參閱 [CLI 驗證選項](https://platform.claude.com/docs/zh-TW/cli-sdks-libraries/cli/authentication)。
      </Step>

      <Step title="發出您的第一個 API 呼叫">
        從您的終端機執行 `ant messages create`：

        ```bash CLI
        ant messages create \
          --model claude-opus-5-5 \
          --max-tokens 1000 \
          --message '{
            role: user,
            content: "What should I search for to find the latest developments in renewable energy?"
          }'
        ```

        CLI 會印出 JSON 回應：

        ```json Output
        {
          "model": "claude-opus-5-5",
          "id": "msg_01N1ycuCkM5Mzd7WhTU4fwST",

            }
          ],
          "stop_reason": "end_turn",
