  "markdown": "Hello! How can I help you today?",
  "html": "<p>Hello! How can I help you today?</p>"
}
```

## Limitations

It is important to note that ChatGPT API is provided on a best-effort basis and may not always be available. Additionally, the API may be rate-limited or have other usage restrictions in place. It is recommended to use the API responsibly and in accordance with any terms of service that may be in place.

## Examples
Here are example codes for using the API in Node.js, Python, and C#:

### Node.js

To use the ChatGPT API in Node.js, you can use the `axios` library to send an HTTP GET request to the API endpoint. Here is an example of how to do this:

```javascript
const axios = require('axios');

async function getResponse(text, lang) {
  try {
    const response = await axios.get('https://api.pawan.krd/chat/gpt', {
      params: {
        text,
        lang
      }
    });
    return response.data;
  } catch (error) {
    console.error(error);
  }
}

getResponse('Hello', 'en').then(response => {
  console.log(response);
});
```

### Python

To use the ChatGPT API in Python, you can use the `requests` library to send an HTTP GET request to the API endpoint. Here is an example of how to do this:

```python
import requests

def get_response(text, lang):
  params = {'text': text, 'lang': lang}
  response = requests.get('https://api.pawan.krd/chat/gpt', params=params)
  return response.json()

response = get_response('Hello', 'en')
print(response)
```

### C#

To use the ChatGPT API in C#, you can use the `HttpClient` class to send an HTTP GET request to the API endpoint. Here is an example of how to do this:

```csharp
using System.Net.Http;
using Newtonsoft.Json;

async Task<Response> GetResponse(string text, string lang) {
  using (var client = new HttpClient()) {
    var queryString = $"text={text}&lang={lang}";
    var response = await client.GetAsync($"https://api.pawan.krd/chat/gpt?{queryString}");
    var responseData = await response.Content.ReadAsStringAsync();
    return JsonConvert.DeserializeObject<Response>(responseData);
  }
}

var response = await GetResponse("Hello", "en");
Console.log(response);
```

Note that these are just basic examples, and you may need to add additional error handling and other functionality as needed for your use case.
