CS2 Skin Price Data from Clash
TradeUpX uses EUR skin prices collected directly from Clash for scanner, calculator, skin, collection and Covert-to-Gold estimates. This page explains how the refresh works, what the coverage number means, and why every market estimate should still be verified before a trade.
Open the Trade-Up Scanner →How TradeUpX Collects Clash Prices
Every refresh starts with the official Clash inventory endpoint. Because that legacy bulk endpoint can be unavailable, TradeUpX can continue through Clash's own public Stash pages. Those pages expose EUR values for the wear variants that Clash currently tracks.
The importer maps each value to its complete Steam market hash name, including weapon, finish, StatTrak or Souvenir prefix, and wear. No second marketplace is blended into the automatic price cache. That keeps one consistent source across the regular scanner, inventory calculations, skin pages and Gold trade-up estimates.
Coverage and Validation Before Publishing
A refresh is accepted only after TradeUpX discovers at least 95% of the expected skin pages and receives usable prices from at least 90% of them. It also requires thousands of distinct wear-specific entries. If those checks fail, the last verified cache remains active instead of replacing good data with a partial response.
The current source, item count, cache age and coverage are exposed by the site's price status. A missing price stays missing; TradeUpX does not invent a value or silently substitute a different marketplace. This may exclude a contract from results, but it prevents false expected-value calculations.
How Price Data Affects EV and ROI
For each possible output, the calculator multiplies its Clash price by its probability and applies the selected market fee. Input prices are added to obtain total contract cost. ROI is then based on probability-weighted net output value rather than the most valuable possible result.
Cached data is useful for comparing thousands of combinations quickly, but CS2 prices and liquidity can move between refreshes. Before buying inputs, open the current market listing and confirm both price and available quantity. Treat TradeUpX as a screening and calculation tool, not as a guaranteed executable quote.
