An autonomous B2B marketing creative pipeline connecting an OpenAI GPT-4o prompt engineering agent with Google Cloud Vertex AI Imagen 3 (via Service Account JWT assertion) and Supabase Storage & PostgreSQL persistence, serving as the upstream asset generator for tomorrow's distribution puzzle.
- Chains autonomous prompt synthesis (GPT-4o + Simple Memory) with Google Vertex AI Imagen 3 predict API and Supabase Storage
- Automates Google Cloud OAuth2 bearer token acquisition via cryptographically signed RS256 JWT service account assertions
- Encodes and uploads generated 8-bit PNG binaries directly to Supabase Object Storage bucket 'generated-images'
- Persists creative records in PostgreSQL with status 'ready_for_distribution' to directly feed tomorrow's connected distribution puzzle (#38)
- Features interactive n8n dark canvas with live step-through execution animation, prompt crafter studio, and asset inspector
- Includes automated 8-point in-browser diagnostic test suite verifying token exchange, Vertex payload schema, and Supabase upsert
Built with: n8n, Google Vertex AI, Imagen 3, Supabase Storage, Supabase Database, OpenAI GPT-4o, LangChain, JWT RS256, Google Cloud OAuth2, Python
