+## 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.
