Pola

Interactive Experience

Pola is a 3D open-air market I built for the Kapruka Agent Challenge 2026. Instead of a chat widget, the interface is a small hand-built village — customers walk between seven lit pavilions, each staffed by an AI shopkeeper with its own personality and territory, from fresh food to fashion to an age-gated lounge. Every shopkeeper runs real agentic tool calls against Kapruka's live commerce MCP for search, delivery estimates, cart, and checkout.

The backend is FastAPI, routed through a three-provider fallback chain (Gemini → Cerebras → Groq) so the whole system stays online at zero hosting cost, no matter which provider is rate-limited at a given moment.

A full write-up covering every architectural decision behind this project — from the world-building to the checkout flow — is available in the essays section.
