### API Key Management

Once you have your API key, you can manage it through your dashboard:

* **View usage**: Monitor your API calls and token usage
* **Regenerate keys**: Create new keys if needed
* **Set limits**: Configure rate limits and usage alerts

## Installation

Below are the instructions to install and initialize the Sqwish client library in your preferred language:

<Tabs>
  <Tab title="Python">
    ```python theme={null}
    pip install sqwishai

    # Then set your API key as an environment variable or in your code:
    # import os
    # os.environ["SQWISH_API_KEY"] = "YOUR_API_KEY"
    ```
  </Tab>

  <Tab title="JavaScript">
    ```javascript theme={null}
    npm install sqwishai

    // Then set your API key as an environment variable
    // process.env.SQWISH_API_KEY = "YOUR_API_KEY"
    ```
  </Tab>

  <Tab title="cURL">
    ```bash theme={null}
    # There's no installation via curl. 
    # Just ensure you have an API key. E.g.:
    # export SQWISH_API_KEY=YOUR_API_KEY
    ```
  </Tab>
</Tabs>

## Environment Variables

Set your API key as an environment variable:

### Linux/macOS

```bash theme={null}
export SQWISH_API_KEY=your_api_key_here
```

### Windows

```cmd theme={null}
set SQWISH_API_KEY=your_api_key_here
```

### Using .env file

Create a `.env` file in your project root:

```bash theme={null}
SQWISH_API_KEY=your_api_key_here
```

Then load it in your application:

<Tabs>
  <Tab title="Python">
    ```python theme={null}
    from dotenv import load_dotenv
    import os

    load_dotenv()  # Load environment variables from .env file
    api_key = os.getenv("SQWISH_API_KEY")
    ```
  </Tab>

  <Tab title="JavaScript">
    ```javascript theme={null}
    require('dotenv').config();
    const apiKey = process.env.SQWISH_API_KEY;
    ```
  </Tab>
</Tabs>

## Quick Test

Once you have your API key set up, you can test it with a simple request:

<Tabs>
  <Tab title="Python">
    ```python theme={null}
    from sqwishai import Sqwish
    import os

    # Initialize the client
    sqwish_client = Sqwish(os.environ.get("SQWISH_API_KEY"))

    # Test with a simple prompt
    test_prompt = "Hello, this is a test prompt."
    response = sqwish_client.text.optimize(test_prompt)

    print(f"Original: {test_prompt}")
    print(f"Optimized: {response}")
    ```
  </Tab>

  <Tab title="JavaScript">
    ```javascript theme={null}
    const { Sqwish } = require('sqwishai');

    // Initialize the client
    const sqwishClient = new Sqwish(process.env.SQWISH_API_KEY);

    // Test with a simple prompt
    const testPrompt = "Hello, this is a test prompt.";
    const response = sqwishClient.text.optimize(testPrompt);

    console.log(`Original: ${testPrompt}`);
    console.log(`Optimized: ${response}`);
    ```
  </Tab>

  <Tab title="cURL">
    ```bash theme={null}
    curl -X POST "https://api.sqwish.ai/v1/optimization/optimize" \
      -H "Content-Type: application/json" \
      -H "Authorization: Bearer $SQWISH_API_KEY" \
      -d '{
        "text": "Hello, this is a test prompt."
    }'
    ```
  </Tab>
</Tabs>
