Is the OpenSkin Pricing API free?
Yes. The Pricing API is free, requires no account or API key, and will remain free in good faith to the CS2 community. It provides prices and market data from Steam, Skinport, Buff163, YouPin, and CSFloat.
Why OpenSkin?
Compare OpenSkin with other CS2 data services for current prices, price history, pattern prices, inventories, inspect links, item images, Steam accounts, and trades.
Marketplace prices
OpenSkin returns Steam, Skinport, Buff163, YouPin, and CSFloat prices under the same full Steam item name and converts prices to USD.
Variant pricing
Doppler phases, Case Hardened paint-seed tiers, and Fade patterns are priced as distinct variants instead of one blended item.
Price times
Each marketplace and type of price has its own collection schedule. Every response says when each price was checked.
