I built a free site that scans eBay every day for Pokémon cards worth grading (PSA 10 upside vs. raw price)

I collect Pokémon cards and kept doing the same thing: scroll eBay for hours looking for raw cards that could come back a PSA 10, then check what a PSA 10 actually sells for. So I built CardHunt to do that part for me. What it does - Scans eBay every day for Pokémon cards and shows the raw price next to what a PSA 10 sells for, so you see the upside at a glance - Our AI looks at the listing photos (centering, corners, edges) and picks the strongest grading candidates, grou

AI 分析

痛点:卡牌收藏者需要花数小时在 eBay 上手动筛选可能有 PSA 10 升值空间的裸卡,并逐一查询 PSA 10 实际成交价,流程繁琐且信息不对称。

目标用户:Pokémon 及其他集换式卡牌收藏者、以送评套利为目的的业余玩家与小卖家。

证据:kept doing the same thing: scroll eBay for hours looking for raw cards that could come back a PSA 10, then check what a PSA 10 actually sells for. So I built CardHunt to do that part for me. / supporters see them the moment we find them (that's how I keep the lights on)

变现:Freemium 订阅:免费浏览(新发现延迟 24 小时解锁),付费 supporter 即时查看最新高潜力卡;后续可扩展为按卡组/价格区间付费、送评代拍佣金或 API 数据订阅。

MVP:两周内可做:用 eBay Browse API 每日抓取 Pokémon 卡 listing,抓取 PSA 10 近期成交价做价差排序,先只做规则化筛选(如标题关键词 + 卖家图片质量 + 价差比),人工/简单启发式判断成色,不做自研 AI 模型;用 Stripe 加一个 '提前 24 小时查看' 的订阅按钮验证付费意愿。

竞品:GemRate、Card Ladder、130point、PSA APR 价格工具

摘要:一位 Pokémon 卡收藏者因厌倦每天花数小时在 eBay 上找有 PSA 10 升值空间的裸卡,用 Next.js + FastAPI + Postgres 自建了 CardHunt,每日扫描 eBay 并对比裸卡价与 PSA 10 成交价,还用自研小模型从照片评估居中/边角/边框。网站免费浏览、无账号即可用,付费 supporter 可提前 24 小时看到新发现,作者称这是 '维持运营' 的方式,说明该利基已存在真实付费意愿,但同类卡牌估值工具竞争较激烈。
