Novita AI proporciona una API de compatibilidad que te permite usar el SDK de Anthropic con los modelos de Novita AI. Esto resulta útil si ya utilizas el SDK de Anthropic y quieres cambiar a los modelos de Novita AI.

## Modelos compatibles

Actualmente, solo los siguientes modelos son compatibles con el SDK de Anthropic:

<AnthropicCompatibilityModels />

## Guía de inicio rápido

Esta guía muestra cómo usar el SDK de Anthropic con los modelos de Novita AI paso a paso.

### 1. Instala el SDK de Anthropic

<CodeGroup>
  ```bash Python icon="python" theme={"system"}
  pip install anthropic
  ```

  ```bash TypeScript icon="js" theme={"system"}
  npm install @anthropic-ai/sdk
  ```
</CodeGroup>

### 2. Inicializa el cliente

Los SDK de Anthropic están diseñados para obtener la clave de API y la URL base de las variables de entorno: `ANTHROPIC_API_KEY` y `ANTHROPIC_BASE_URL`. Además, puedes proporcionar los parámetros al cliente de Anthropic al inicializarlo.

<Tip>
  Puedes ver y administrar tus claves de API en la [página de configuración](https://novita.ai/settings/key-management?utm_source=getstarted).
</Tip>

* Usando variables de entorno

<CodeGroup>
  ```bash Bash icon="terminal" theme={"system"}
  export ANTHROPIC_BASE_URL="https://api.novita.ai/anthropic"
  export ANTHROPIC_API_KEY="<YOUR_NOVITA_API_KEY>"
  ```
</CodeGroup>

* Establece los parámetros al inicializar el cliente de Anthropic

<CodeGroup>
  ```python Python icon="python" theme={"system"}
  import anthropic

  client = anthropic.Anthropic(
      base_url="https://api.novita.ai/anthropic",
      api_key="<YOUR_NOVITA_API_KEY>",
      # Rewrite header
      default_headers={
          "Content-Type": "application/json",
          "Authorization": "Bearer <YOUR_NOVITA_API_KEY>",
      }
  )
  ```

  ```typescript TypeScript icon="js" theme={"system"}
  import Anthropic from "@anthropic-ai/sdk";

  const anthropic = new Anthropic({
      baseURL: "https://api.novita.ai/anthropic",
      apiKey: "<YOUR_NOVITA_API_KEY>",
      // Rewrite header
      defaultHeaders: {
        "Content-Type": "application/json",
        Authorization: `Bearer <YOUR_NOVITA_API_KEY>`,
      }
  });
  ```
</CodeGroup>

### 3. Llama a la API

<CodeGroup>
  ```python Python icon="python" theme={"system"}
  import anthropic

  # Initialize the client, if you already set `ANTHROPIC_BASE_URL` and `ANTHROPIC_API_KEY` 
  # in the environment variables, you can omit the `api_key` and `base_url` parameters.
  client = anthropic.Anthropic(
      base_url="https://api.novita.ai/anthropic",
      api_key="<YOUR_NOVITA_API_KEY>",
      # Rewrite header
      default_headers={
          "Content-Type": "application/json",
          "Authorization": "Bearer <YOUR_NOVITA_API_KEY>",
      }
  )

  message = client.messages.create(
      model="moonshotai/kimi-k2-instruct",
      max_tokens=1000,
      temperature=1,
      system=[
          {
              "type": "text",
              "text": "You are a world-class poet. Respond only with short poems."
          }
      ],
      messages=[
          {
              "role": "user",
              "content": [
                  {
                      "type": "text",
                      "text": "Why is the ocean salty?"
                  }
              ]
          }
      ]
  )

  print(message.content)
  ```

  ```typescript TypeScript icon="js" theme={"system"}
  import Anthropic from "@anthropic-ai/sdk";

  // Initialize the client, if you already set `ANTHROPIC_BASE_URL` and `ANTHROPIC_API_KEY` 
  // in the environment variables, you can omit the `baseURL` and `apiKey` parameters.
  const anthropic = new Anthropic({
      baseURL: "https://api.novita.ai/anthropic",
      apiKey: "<YOUR_NOVITA_API_KEY>",
      // Rewrite header
      defaultHeaders: {
        "Content-Type": "application/json",
        Authorization: `Bearer <YOUR_NOVITA_API_KEY>`,
      }
  });

  const msg = await anthropic.messages.create({
    model: "moonshotai/kimi-k2-instruct",
    max_tokens: 1000,
    temperature: 1,
    system="You are a world-class poet. Respond only with short poems.",
    messages: [
      {
        role: "user",
        content: [
          {
            type: "text",
            text: "Why is the ocean salty?"
          }
        ]
      }
    ]
  });

  console.log(msg);
  ```
