How this works
Method. Every Monday we call Olive Young Global's public ranking API and store the Korea and US charts —
rank, product, brand, rating, price. Facts only. We respect the site's robots.txt and its
5-second crawl delay, and we don't copy images or review text.
What the gap means. "US" here is what US customers order on Olive Young Global — not US retail availability. So the gap is a discovery gap, not an availability gap. When we add Ulta, Sephora and Target via their affiliate APIs, we'll report true retail availability separately.
Why weekly. Rankings can't be collected retroactively. Every week we snapshot is a week nobody else has.
