About Steam Data API
What is Steam Data API?
Steam Data API is a developer-focused API that delivers live market prices for CS2 and Rust items, including skins, stickers, and cases. It aggregates listings from 10+ marketplaces, normalizes prices to USD cents, and returns clean JSON—making it easy to build trading sites, bots, and analytics dashboards.
What problem does it solve?
Manually tracking prices across multiple marketplaces is time-consuming and error-prone. Steam Data API solves this by sweeping live prices continuously, providing daily median history back to 2013, and exposing Doppler phases separately (e.g., Ruby, Sapphire) for accurate valuations. It also offers an inventory endpoint to value entire Steam inventories with floats and total worth.
Who is it for?
Ideal for developers and businesses running trading platforms, arbitrage bots, Discord/Telegram price bots, or market analytics tools. Not suited for casual gamers looking for a UI—this is a raw API requiring coding skills.
Real use cases
Price comparison sites surface the best live deal; inventory worth calculators paste a SteamID and get a portfolio total; trading bots spot cross-market spreads and act in milliseconds; charting tools visualize six years of history.
