This is a JWT-authenticated gateway to Google Vertex AI's Gemini models via LangChain. You register and log in through bcrypt-secured endpoints, get a JWT token, then use it to hit a completion endpoint that routes your prompt through LangChain's orchestration layer before hitting Gemini. It's one of several agents in the GOSCE portfolio, all built by an automated pipeline that scans GitHub dependencies and spins up monetizable combinations as MCP servers. The auth layer makes it suitable when you need metered access or user-scoped LLM calls rather than direct API keys. Part of the getvda.ai hosted agent ecosystem with x402 micropayment support.
