I built a tool to help sports-card collectors find potential deals

I’ve been buying and selling sports cards, and one problem I kept running into was figuring out if a card was actually a good deal. Checking sold listings manually takes time, and a lot of listings don’t make it easy to compare prices. So I built Slab Scout . You can search for a card and use recent sales to get a better idea of its market value. The goal is to make it easier to find cards that may be listed below what they’re actually selling for. https://slabscout.lovable.app/ It

证据:one problem I kept running into was figuring out if a card was actually a good deal. Checking sold listings manually takes time;make it easier to find cards that may be listed below what they’re actually selling for.

变现:免费增值:基础估价免费,付费订阅提供实时降价提醒、Portfolio跟踪、跨市场扫描、高级成交数据/API;联盟返佣导流到eBay/拍卖平台。

MVP:做一个浏览器扩展或轻量Web应用,在eBay/COMC商品页嵌入近期成交价、估价区间和deal score,先支持棒球/篮球卡的一个市场,用eBay sold data或第三方API,允许用户手动修正comps。

竞品:Card Ladder、130point、Market Movers、PSA APR、eBay Terapeak、Sports Card Investor
