# AI Social Media Pipeline - Imagen + Meta Graph API Automated pipeline that takes an AI-generated cybersecurity image from Supabase, writes platform-specific captions via two AI agents, and posts to Facebook and Instagram using the Meta Graph API. ## The Problem Security founders spend hours writing captions and manually posting content across platforms. It doesn't scale. ## The Solution n8n workflow: Fetch image from Supabase → Agent 1 writes IG caption → Agent 2 writes FB caption → Post to Instagram via container flow → Post to Facebook directly. ## Use Cases - Automated cybersecurity brand content - Daily social media posting without manual work - Multi-platform content distribution from one pipeline ## Tech Stack - n8n (orchestration) - Supabase Storage (image source) - OpenAI GPT-4o (caption agents) - Meta Graph API (Facebook + Instagram) - Vertex AI Imagen 4 (image source from puzzle #37) ## Target Audience MDR founders, GRC consultants, security company operators running lean marketing ## Impact Eliminates 1-2 hours daily of manual social posting. Fully automated end to end. image brave_screenshot_etxn8n etxhuman com Built by Kunsh Tanwar | ETXcyberops | kunsh@etxhuman.com
