Recommended: run the included server.js with your eBay App ID + Cert ID in .env. The kiosk will detect it automatically and show live listings (auto-refreshing every 5 minutes).
Fallback (no server): paste an Application Access Token below. Tokens last ~2 hours.
Go to developer.ebay.com → My Account → Application Keys.
Open OAuth → Application Access Token, scope https://api.ebay.com/oauth/api_scope, click Get token.
