致各代购平台的一封公开信
An open letter to shopping agents
2026-09-24 · English version ↓
每周约有 3,000 次，买家从 QCradar 点击前往代购平台购买，对应的商品总价值约 30 万元，这两个数字都还在稳步上涨。我们支持代购平台核验 QCradar 的后台数据。我们的目标是成为代购圈最大的 QC 与导购站，接下来还有多项重要功能陆续上线。
买家在决定去哪家代购购买时，最在意两件事。我们推荐代购平台，也只看这两件事。
一、通过接口开放 QC 图片
发货之前，买家靠 QC 图片判断货品质量。平台持续有新的 QC 图出来，也说明它还在正常收货、发货。买家已经学会看这一点，因为这是判断一家平台是否在正常运营的最直接依据。
我们的请求： 提供一个只读接口，按商品链接返回对应的 QC 图片（附验货日期）。不涉及任何用户或订单数据。查看 QC 接口对接文档
二、一键导入购物车
买家在这里挑好一整单，再把链接一条条复制到代购平台。有了批量导入，这件事点一下就能完成，尺码也会提前选好。
我们的请求： 提供一个接口，接收一组商品（商品链接、SKU、数量），把它们放进买家的购物车。导入格式公开，任何表格站或工具都可以用，不只是 QCradar。查看购物车导入对接文档
我们怎样推荐代购平台
两项都支持的平台，会出现在我们的推荐位。标准只有这两条，推荐位不出售。
目前两项都已支持的平台：LoongBuy、OopBuy。
想加入？
两份文档都已公开，工程师半天就能看完。签名算法相同，一套凭据就能接两个接口。

Every week, buyers click through from QCradar to a shopping agent about 3,000 times, for goods worth roughly ¥300,000 (about $42,000). Both numbers are growing steadily, and we're happy to let agents verify our backend data. Our goal is to become the largest QC and buying-guide site in the community, and several major features are on the way.
When buyers choose which agent to buy through, two things matter most to them. They're also the only two things we look at when recommending an agent.
1. QC photos, available through an API
QC photos are how buyers judge quality before anything ships. A steady flow of new QC photos also shows that an agent is still receiving and shipping orders. Buyers have learned to look for this, because it's the clearest evidence that an agent is operating normally.
What we ask: a read-only API that returns the QC photos (with inspection dates) for a given product link. No user or order data is involved. Read the QC API spec
2. One-click cart import
Buyers put together a full haul here, then copy the links into an agent one by one. With batch import, that takes a single click, with sizes pre-selected.
What we ask: an endpoint that takes a list of items (product link, SKU, quantity) and puts them in the buyer's cart. The format is public, so any spreadsheet site or tool can use it, not only QCradar. Read the cart import spec
How we recommend agents
Agents that support both are featured in our recommendations. These are the only two criteria, and recommendation spots are not for sale.
Agents that support both today: LoongBuy, OopBuy.

Both specs are public, and an engineer can read them in half a day. They share the same signing scheme, so one set of credentials covers both.
