Overview
Instantly see RRP, piece count and retirement status for Lego sets while browsing Vinted.
SetCheck is a browser extension built for Lego buyers and resellers on Vinted. While you browse, it automatically detects the Lego set number in a listing and shows you: - Official retail price (RRP) and how the asking price compares - Piece count and minifig count - Whether the set is retired or still in production - Whether the listing is sealed (new with/without tag) or opened - For listings with multiple sets bundled together, a combined deal score across all sets found No more manually looking up set numbers or doing price-per-piece math — SetCheck surfaces it right on the listing page. Setup: SetCheck uses the free Brickset API. After installing, grab a free API key at brickset.com/tools/webservices/requestkey and paste it into the extension popup — takes about a minute. Privacy: SetCheck only reads Vinted listing content to detect set numbers, and only sends the detected set number (plus your own API key) to Brickset. No tracking, no analytics, no data collection.
