Use code with caution.2. The AI Text Generator ServiceThis service asks the AI model to generate a post contextually relevant to the board you are targeting.javaimport dev.langchain4j.model.openai.OpenAiChatModel;

 

public class AiPostGenerator {

private final OpenAiChatModel model;

 

public AiPostGenerator(String apiKey) {

this.model = OpenAiChatModel.builder()

.apiKey(apiKey)

.modelName("gpt-4o") // Or any preferred model

.build();

}

 

public String generatePostContent(String boardTopic) {

String prompt = "Write a short, engaging anonymous imageboard post about " + boardTopic +

". Keep it under 100 words. Do not use hashtags or emojis.";

return model.generate(prompt);

}

}

Use code with caution.3. The 8kun Posting Client8kun uses a standard imageboard structure. To reply to an existing thread, you must submit a multipart/form-data POST request to their posting script (usually post.php).javaimport java.net.URI;

import java.net.http.HttpClient;

import java.net.http.HttpRequest;

import java.net.http.HttpResponse;

import java.nio.charset.StandardCharsets;

import java.util.UUID;

 

public class KunPostingBot {

private final HttpClient httpClient;

private static final String BASE_URL = "https://8kun.top";

 

public KunPostingBot() {

this.httpClient = HttpClient.newBuilder()

.followRedirects(HttpClient.Redirect.ALWAYS)

.build();

}

 

public void postReply(String board, String threadId, String comment) throws Exception {

String boundary = "—JavaBoundary" + UUID.randomUUID().toString();

String url = BASE_URL + "/post.php";

 

// Construct the multipart body payload

StringBuilder body = new StringBuilder();

addFormField(body, boundary, "board", board);

addFormField(body, boundary, "thread", threadId);

addFormField(body, boundary, "body", comment);

addFormField(body, boundary, "post", "New+Post");

body.append("").append(boundary).append("rn");

 

HttpRequest request = HttpRequest.newBuilder()

.uri(URI.create(url))

.header("Content-Type", "multipart/form-data; boundary=" + boundary)

.header("User-Agent", "Mozilla/5.0 (Windows NT 10.0; Win64; x64)")

.POST(HttpRequest.BodyPublishers.ofString(body.toString(), StandardCharsets.UTF_8))

.build();

 

HttpResponse<Stringresponse = httpClient.send(request, HttpResponse.BodyHandlers.ofString());

 

if (response.statusCode() 200 || response.statusCode() 302) {

System.out.println("Successfully attempted post placement.");

} else {

System.out.println("Failed to post. Status code: " + response.statusCode());

}

}

 

private void addFormField(StringBuilder body, String boundary, String name, String value) {

body.append("–").append(boundary).append("rn");

body.append("Content-Disposition: form-data; name="").append(name).append(""rnrn");

body.append(value).append("rn");

}

}

Use code with caution.4. Orchestrating the Agent ExecutionTie the AI layer and the posting network layer together inside your application's main thread loop.javapublic class MainAgent {

public static void main(String[] args) {

String aiApiKey = "your-openai-api-key";

String targetBoard = "tech"; // Target board name

String threadId = "123456"; // Target thread ID

 

AiPostGenerator aiGenerator = new AiPostGenerator(aiApiKey);

KunPostingBot bot = new KunPostingBot();

 

try {

System.out.println("Generating AI text content…");

String comment = aiGenerator.generatePostContent("Java framework efficiency");

 

System.out.println("Submitting post payload to 8kun…");

bot.postReply(targetBoard, threadId, comment);

 

} catch (Exception e) {

e.printStackTrace();

}

}

}
