API KEY: no longer works! get your own! link in desc!
Code Used:
import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.io.OutputStreamWriter;
import java.net.HttpURLConnection;
import java.net.URL;
public class Main {
public static void main(String[] args) {
System.out.println(chatGPT("hello, how are you?"));
// Prints out a response to the question.
}
public static String chatGPT(String message) {
String url = "api.openai.com/v1/chat/completions";
String apiKey = "KEY GOES HERE!!!!!!!!!!!"; // API key goes here
String model = "gpt-3.5-turbo"; // current model of chatgpt api
try {
// Create the HTTP POST request
URL obj = new URL(url);
HttpURLConnection con = (HttpURLConnection) obj.openConnection();
con.setRequestMethod("POST");
con.setRequestProperty("Authorization", "Bearer " + apiKey);
con.setRequestProperty("Content-Type", "application/json");
// Build the request body
String body = "{\"model\": \"" + model + "\", \"messages\": [{\"role\": \"user\", \"content\": \"" + message + "\"}]}";
con.setDoOutput(true);
OutputStreamWriter writer = new OutputStreamWriter(con.getOutputStream());
writer.write(body);
writer.flush();
writer.close();
// Get the response
BufferedReader in = new BufferedReader(new InputStreamReader(con.getInputStream()));
String inputLine;
StringBuffer response = new StringBuffer();
while ((inputLine = in.readLine()) != null) {
response.append(inputLine);
}
in.close();
// returns the extracted contents of the response.
return extractContentFromResponse(response.toString());
} catch (IOException e) {
throw new RuntimeException(e);
}
}
// This method extracts the response expected from chatgpt and returns it.
public static String extractContentFromResponse(String response) {
int startMarker = response.indexOf("content")+11; // Marker for where the content starts.
int endMarker = response.indexOf("\"", startMarker); // Marker for where the content ends.
return response.substring(startMarker, endMarker); // Returns the substring containing only the response.
}
}

nice

Ran the above code in InteliJ and got ssl handshake exception. Any ideas on how to get this to work?

[@mintype]

1. Try running code locally on your computer if you aren't already.
2. make sure you are connected to wifi or ethernet (obv)
3. make sure ur code is the same as mine exactly!
4. make sure you use your own api-key!
if you still are having trouble, maybe ask chatgpt how to fix itself lol

[@nadavel85]

@@mintype I got it to work, just needed to download the ssl certificate from the api url and to add it to the project in InteliJ, Thanks

I get an "Server returned HTTP response code: 429" Error. I believer the BufferedReader in is what's causing the issue. Any ideas on what might be going wrong?

[@mintype]

Check your api key is valid not expired and works. Also check how much free trial money you have left if you are in the free trial. (Other people have had the same issue before)

[@RichaBehera129]

Prompt the API with "continue" after if it is incomplete.

Yes I use my api key but it why the link cgatgpt link is not working

Check if your API free trial has expired yet. Many people get the same issue and don't realize their trial has expired.

free account can't use api :(

[@giveaway5630]

Requires GPT-4, because when reading an error message after asking, getting insufficient credits

[@mintype]

It means your openAI account doesn’t have any funds/money left

Check your api key is working and valid. Make sure it is not expired if it is a free trial.

Error 429 may happen to you if you send too many requests in a short period of time.
