Could you build this?
Partial The index site and weekly calculations are easy to build, but the product depends on continuously collecting sold and ask data from GOAT, StockX, Mercari, and Chrono24. Those sites actively block scraping and restrict their data, so a reliable data pipeline is the hard piece.
What it would actually take: The stack is a scheduled scraper or data pipeline feeding a database, then a statistics layer that computes median prices, sample sizes, and fee-adjusted net, and a static front end. The hard parts are obtaining sold-price data legally and reliably despite anti-bot defenses, and cleaning matches across product variants. This requires data engineering and sourcing relationships, or licensed data.
