⚙️ Key Components

| Node | Function | |------|-----------| | Schedule Trigger | Runs automatically at chosen intervals to start meme generation. | | Define Memecoin | Defines mascot name, description, and base image URL. | | AI Agent | Generates tweet text and creative image prompt using Google Gemini. | | Google Gemini Chat Model | Provides trending topic context and meme phrasing. | | Get Source Image | Fetches the original mascot image (e.g., Popcat). | | Convert Source Image to Base64 | Prepares image for AI based remixing. | | Generate Image using NanoBanana | Sends the prompt and base image to Gemini Image API for art generation. | | Convert Base64 to PNG | Converts the AI output to an image file. | | Upload to Twitter | Uploads generated image to Twitter via media upload API. | | Create Tweet | Publishes the tweet with attached image. |

🪄 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.
