NOSTOS

market.nostos/nostos

Connects Claude to live inventory, pricing, and trade-in data from a retro gaming store in Duluth, GA. You can query what's in stock across categories like Super Famicom, PC Engine, Neo Geo, and other Japanese imports, get real-time buy and sell prices for games and consoles, check store hours and location details, and pull trade-in estimates before making a trip. Useful if you're building tools for collectors tracking availability, comparing trade-in offers across stores, or just need a dataset of current retro game market prices. The store itself ships to US and Canada, with a physical location opening mid-2026, so the API likely surfaces both online catalog and regional inventory.
