Automatically generates memecoin art and posts it to Twitter (X) powered by Google Gemini, NanoBanana image generation, and n8n automation.

🧩 Overview

This workflow creates viral style memecoin images (like Popcat) and posts them directly to Twitter with a witty, Gen Z style tweet.

It combines text to image AI, scheduled triggers, and social publishing, all in one seamless flow.

Workflow flow:

1. Define your memecoin mascot (name, description, and base image URL).
2. Generate an AI image prompt and a meme tweet.
3. Feed the base mascot image into Gemini Image Generation API.
4. Render a futuristic memecoin artwork using NanoBanana.
5. Upload the final image and tweet automatically to Twitter.

🪄 How It Works

1️⃣ Schedule Trigger - starts the automation (e.g., hourly or daily).
2️⃣ Define Memecoin - stores your mascot metadata:

memecoin_name: popcat
mascot_description: cat with open mouth
mascot_image: https://i.pinimg.com/736x/9d/05/6b/9d056b5b97c0513a4fc9d9cd93304a05.jpg

3️⃣ AI Agent - prompts Gemini to:

• Write a short 100 character tweet in Gen Z slang.
• Create an image generation prompt inspired by current meme trends.
  4️⃣ NanoBanana API - applies your base image + AI prompt to create art.
  5️⃣ Upload & Tweet - final image gets uploaded and posted automatically.
