OpenSkin
OpenSkin is a CS2 development platform with a free skin pricing API, interactive 3D viewer, item images, inventories, inspect-link data, and Steam tools.
What the free API provides
Current CS2 prices, order books, price history, and pattern-specific market data from Steam and supported third-party marketplaces. The public v1 pricing endpoints do not require an API key.
Start with the API
Use the quickstart for a single item, batch requests for up to 500 names, or the bulk endpoint for a complete catalog sync.
