SecondLoop helps community groups find reusable surplus items that fit their needs and collection constraints. Users describe an intended outcome, such as creating a community garden using supplies they can collect by scooter. The prototype combines map-based listings with a backend Meta AI tool-calling integration that searches inventory, checks constraints, and creates match proposals. Backend code validates availability, quantities, straight-line distance, and known transport limits. Missing measurements remain unknown. Users explicitly confirm pickup requests, then track donor confirmation, scheduling, collection, completion with a demo code, or cancellation with history preserved. Built with React, ASP.NET Core, PostgreSQL/PostGIS, and Leaflet, SecondLoop uses synthetic demo data and clearly labeled demo identities. A deterministic Demo Mode supports demonstrations when Meta API credentials are unavailable; live inference verification remains pending.
