⚙️ 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).

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.
