I built a site that shows what used cameras are actually worth, from real sales at 10 shops

Context: I run a used camera store online as a side project. Have done so for a few months now. Reliably finding used price estimates was the biggest hurdle at the beginning and I wanted to share information for others to use as well. Such sites do not really exist, and the ones that do, are mostly affiliate marketing spam. So I built Kamarvo (kamarvo.com).

AI 分析

痛点：二手相机与镜头缺乏可信的价格参考，现有查询网站大多是联盟营销垃圾内容，买卖双方无法判断真实成交价。

目标用户：二手相机/镜头的买家与卖家、小型二手器材商家、以旧换新的个人用户

证据：Reliably finding used price estimates was the biggest hurdle at the beginning... Such sites do not really exist, and the ones that do, are mostly affiliate marketing spam. / It's free, with no sign-up.

变现：免费查询+联盟导流到二手店赚佣金；面向器材商的付费Pro版（批量估价、库存定价、价格下跌提醒、API）；向比价/回收平台授权已售成交数据。

MVP：两周内做垂直单品类（如索尼E卡口镜头）：爬取eBay sold + MPB + KEH 的成交记录，做型号别名归一化，输出价格走势图、按成色报价和邮件价格提醒，先靠联盟链接变现。

竞品：eBay Sold Listings、MPB、KEH、Camera Price Watch、CollectiBlend、UsedPhotoPro

摘要：作者运营二手相机网店，因找不到可靠价格参考，自建 Kamarvo：每天抓取6国10家二手店的挂牌并识别成交，已追踪10.7万条listing、1.4万款机型、6600+笔成交，模型别名匹配是最大难点。网站目前完全免费、无注册，未披露任何收入或付费用户，但已有联盟营销类竞品证明该流量可变现。
