One platform, multiple products
Each game page connects the available products, item coverage and integration endpoints. The Live Data Explorer lets you inspect a bounded current sample.
Operational proof
Established in 2018 and trusted by developers, marketplaces and trading platforms.
Every supported game has three core products: a Price API for the complete supported item catalogue and current prices, a Market API for current third-party marketplace prices, and an Inventory API for public Steam inventory data.
Select CS2, Rust, Dota 2, TF2 or another supported game to see the correct game parameter, Steam App ID, product pages and documented request examples for each workflow.
Tell the Steamwebapi team what you are building. A short sentence is enough — we will help you identify the right product and the simplest way to integrate it.
