Price tracking
Search for a product or paste a link to see what it costs now and what we have observed it costing. Set a target price and we will email you when it drops below it.
The research behind this, with sources: “Where the prices come from”, below
Where the prices come from
Three Korean affiliate programmes were checked. One of them can lawfully give us a price. The page says so rather than laying itself out as if there were three.
- CoupangPrice via official API
The Coupang Partners open API officially returns both a product price and an affiliate deeplink. Its search endpoint has a low hourly ceiling, so bulk endpoints (category best-sellers, GoldBox) do most of the collecting.
- NaverNo lawful price feed
Naver ended shopping data on its Search API at 24:00 on 2026-07-31 with no replacement. Even before that, its API terms 7.3③ forbade storing or caching results and 7.3④ forbade showing advertising beside them. Shopping Connect offers creators no API.
- Toss ShoppingNo lawful price feed
Toss Sharelink is a share button on a product page that a person presses; no product or price endpoint is published. It cannot be a price source.
How this works
- Prices are readings, not a live feed. Each one says when it was taken and which call produced it.
- Collection runs on a small hourly budget, so a product can go days between readings. Gaps in the chart are gaps in what we saw, not prices we are hiding.
- A “lowest” is the lowest we observed. It is not a claim about the lowest price that ever existed.
