## Prasyarat

* Sebuah [akun Claude Console](https://platform.claude.com)
* Sebuah [kunci API](https://platform.claude.com/docs/id/get-api-key)

## Memanggil API

<Tabs>
  <Tab title="cURL">
    <Steps>
      <Step title="Atur kunci API Anda">
        Ekspor kunci API Anda sebagai variabel lingkungan. Perintah cURL di bawah membacanya dari `$ANTHROPIC_API_KEY`.

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

      <Step title="Lakukan panggilan API pertama Anda">
        Kirim permintaan `POST` ke Messages API:

        ```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 mengembalikan respons JSON yang berisi pesan asisten:

        ```json Output

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

  <Tab title="CLI">
    <Steps>
      <Step title="Instal CLI">
        Instal Anthropic CLI dengan Homebrew:

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

        Untuk metode instalasi lainnya, lihat [Instalasi](https://platform.claude.com/docs/id/cli-sdks-libraries/cli/quickstart#installation) di panduan cepat CLI.
      </Step>

      <Step title="Autentikasi">
        Masuk dengan akun Anthropic Anda:

        ```bash
        ant auth login
        ```

        Ini membuka alur OAuth berbasis browser. Setelah memberikan otorisasi, konfirmasikan kredensial Anda dengan:

        ```bash
        ant auth status
        ```

        Pada host jarak jauh tanpa browser, berikan `--no-browser` untuk mendapatkan URL yang dapat Anda buka di perangkat lain, lalu tempelkan kode yang dikembalikan ke terminal. Jika `ANTHROPIC_API_KEY` diatur di lingkungan Anda, variabel tersebut lebih diutamakan daripada kredensial login. Untuk lingkungan non-interaktif seperti CI, lihat [opsi autentikasi CLI](https://platform.claude.com/docs/id/cli-sdks-libraries/cli/authentication).
      </Step>

      <Step title="Lakukan panggilan API pertama Anda">
        Jalankan `ant messages create` dari terminal Anda:

        ```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 mencetak respons JSON:

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

      <Step title="Atur kunci API Anda">
        Ekspor kunci API Anda sebagai variabel lingkungan. SDK membaca `ANTHROPIC_API_KEY` secara otomatis.

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

      <Step title="Buat proyek dan instal SDK">
        ```bash
        mkdir claude-quickstart && cd claude-quickstart
        bundle init
        bundle add anthropic
        ```
      </Step>

      <Step title="Buat kode Anda">
        Buat file bernama `quickstart.rb`:

        ```ruby Ruby
        require "anthropic"

        client = Anthropic::Client.new

        message = client.messages.create(
          model: Anthropic::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?"
            }
          ]
        )

        message.content.each do |block|
          puts block.text if block.type == :text
        end
        ```
      </Step>

      <Step title="Jalankan kode Anda">
