FAQ
Frequently asked questions
Which marketplaces does the CSPriceAPI extension support?
+
Ten marketplaces. Skinport, CSFloat, Skinplace, LIS-SKINS, Shadowpay work on the free plan, while SkinBaron, DMarket, CS.Money, White.Market, Waxpeer are part of Pro. The overlay behaves the same everywhere: price badges on listing grids and a full comparison panel on item pages.
Is the extension free?
+
Yes. The free plan is permanent and needs no credit card: price badges on listing grids, basic ROI against the listing price, currency conversion and cached snapshot prices. Pro costs $14 per month or $140 per year and unlocks live data, buy orders, charts, alerts and the arbitrage scanner.
Do I need an account to use it?
+
Not for the free features — cached snapshot prices show up right after installing. You only sign in when you want Pro features, using the same cspriceapi.com account as the website.
How current are the prices?
+
On the free plan the overlay serves cached snapshots roughly two hours old. Pro refreshes live prices about every five minutes, which is what matters when you are pricing an item against a moving market.
Does it show Doppler and Gamma Doppler phase prices?
+
Yes, and each phase is priced separately rather than averaged into one number: Phase 1 to 4, Ruby, Sapphire, Black Pearl and Emerald. The extension reads the phase from the listing itself, so a Ruby is never compared against a Phase 2 price.
Does the extension work in Edge, Brave or Opera?
+
Yes. It runs in Chrome and every Chromium-based browser, including Edge, Brave, Opera and Vivaldi — install it from the Chrome Web Store in any of them. A Firefox build is not published yet.
Which currency does the overlay use?
+
It follows the marketplace you are on. If a site displays USD, the comparison prices are shown in USD too, so you never mix currencies while judging a deal. EUR, USD, CNY and other common currencies are supported.
What data does the extension read from marketplace pages?
+
Only what it needs to look up a comparison price: the item name, wear, float value, Doppler phase and the displayed listing price on pages you open yourself. It does not read your browsing history, Steam credentials or inventory, and nothing is sold to third parties.
What makes it different from other CS2 price extensions?
+
It runs on CSPriceAPI's own market data rather than scraping a single site, which is why it covers ten marketplaces, prices every Doppler phase individually, and can show YouPin and BUFF163 buy orders — the number you actually sell at, not just the lowest ask.
