Automated breaking news headlines with LLaMA3, Google Search and X posting

It combines Google Custom Search for finding the latest news articles with Groq's LLaMA 3 model to generate short, engaging headlines — complete with hashtags — and posts them on your X account.

⚙️ How It Works (Step-by-Step)

Trigger

• The workflow starts on a scheduled interval (default: every 5 hours, at a random minute within the hour).

Set Topic

• You can define your own topic keyword (e.g., AI, mental health, climate change) by editing the Set Topic node.

Build Search Query

• Constructs a Google search query like: latest {topic} news.

Google API Config

• Injects your own Google API Key and Custom Search CX (replace the placeholders in the Google Config node).

Search for News

• Performs a real-time search using Google Custom Search API and fetches the latest article result.

Generate Prompt for AI

• A JavaScript Function node extracts the top article’s title and link, formats it into a clean prompt including instructions to append hashtags.

Groq AI Request

• Sends the prompt to Groq’s LLaMA 3 model to generate a concise, tweet-length headline with 1–2 relevant hashtags.

Post to Twitter (X)

• The generated headline is posted to your connected X account via the Twitter OAuth2 API.

✅ Requirements

• Google API Key

• Google Custom Search Engine (CX)

• Groq API Key

• Twitter Developer App with OAuth2 credentials

💡 Customization Tips

• Change the topic in the Set Topic node to anything you like.

• Adjust the posting frequency in the Schedule Trigger node.

• Modify prompt behavior in the Function node to fit a specific tone or brand voice.

• Add logging, filtering, or multiple post variations as needed.
