write html for chatgpt api, dont use server coding like python php, using html only

Unfortunately, HTML alone cannot be used to create an API for chatGPT. APIs require server-side programming languages such as Python, PHP, or JavaScript. HTML is used to create the structure and content of web pages, but it cannot handle data storage, retrieval, or processing required for APIs.

However, if you want to display chatGPT API results on a web page, you can use JavaScript to fetch data from the chatGPT API endpoint and display it on the page. Here's an example of how you can use JavaScript to fetch and display chatGPT API:

<!DOCTYPE html>
<html>
<head>
  <title>ChatGPT API Example</title>
  <script>
    function getChat() {
      // Replace YOUR_API_KEY with your chatGPT API key
      var apiKey = "YOUR_API_KEY";

      // Replace YOUR_MESSAGE with the message you want to send to chatGPT
      var message = "YOUR_MESSAGE";

      // Construct API endpoint URL
      var apiUrl = "https://api.openai.com/v1/engines/davinci-codex/completions?prompt=" + encodeURIComponent(message) + "&max_tokens=100&n=1&stop=";

      // Fetch data from API endpoint
      fetch(apiUrl, {
        headers: {
          "Authorization": "Bearer " + apiKey,
          "Content-Type": "application/json"
        },
      })
      .then(response => response.json())
      .then(data => {
        // Display chatGPT response
        document.getElementById("chat-result").innerHTML = data.choices[0].text;
      })
      .catch(error => console.error(error));
    }
  </script>
</head>
<body>
  <h1>ChatGPT API Example</h1>
  <div>
    <label for="message-input">Type your message:</label>
    <input type="text" id="message-input">
    <button onclick="getChat()">Send</button>
  </div>
  <div>
    <p>ChatGPT response:</p>
    <p id="chat-result"></p>
  </div>
</body>
</html>

This code creates a simple web page with an input field and a button to send a message to chatGPT. When the user clicks the "Send" button, the getChat() function is called. This function constructs the API endpoint URL with the user's message and API key, and then fetches data from the API endpoint using the fetch() function. Once the API response is received, the function updates the web page with the chatGPT response.

Note that this code requires an API key from chatGPT, which you can obtain by signing up for their API program. Also note that this code is just an example and may need to be modified to suit your specific needs.
