Example response

{
  "data": [
    {
      "brand": "Nike",
      "model": "Tech Fleece",
      "sold_7d": 1240,
      "avg_price_eur": 21.4,
      "max_buy_price": 14.2,
      "str_pct": 12.4,
      "top_sizes": ["M", "L", "S"]
    }
  ],
  "count": 1
}

max_buy_price is the highest price you can pay and still clear roughly 30% margin after platform fees. str_pct is the observed share — watched sales divided by watched sales plus still-listed items, capped at 100%. It is withheld (null) below 30 watched sales in the window, or when we have no still-listed sample; null is not 0 and not 100. Weekly turnover (sold_7d / active_listings) is a different statistic and is never labelled sell-through.
