Steam Market API for CS2
Query Steam listings and buy orders through one CS2Cap endpoint. Rather than integrating Steam directly, you get its feed normalized alongside every other marketplace we track.
The Steam Community Market is where most CS2 items originate and where the largest number of players transact, but its prices are quoted in wallet funds that cannot be cashed out, so they run consistently above cash-market equivalents. Reading Steam alongside cash marketplaces is what turns 'this item costs $100' into a decision, and its rate limits make a cached, normalized feed close to mandatory.
CS2Cap tracks 24.3M Steam Community Market listings across 34.8K items, 82.5% of the CS2 catalog, holding $29.2M in listed value. That makes it the 16th-largest listing book of the 41 marketplaces tracked here. The feed refreshes every 40 minutes, with buy orders. Daily Steam Community Market price history runs back to Apr 2013.

Questions
Before you build
Is this an official Steam API?
No. CS2Cap is a third-party aggregation service. Steam data is included as one of many supported marketplace sources.
What data is available from Steam?
CS2Cap returns Steam listing prices, buy orders, refreshed every 40 minutes, with daily history since Apr 2013.
Is Steam the same as Steam Community Market, SCM, Steam Market?
Yes. Steam is also written as Steam Community Market, SCM, Steam Market. Those names all refer to the same marketplace, and this page covers that single feed.
Are Doppler phases and float values priced separately?
No. Steam prices are keyed by item name and Doppler phases are not broken out on this feed. Float value and paint seed appear on individual sale records from marketplaces that publish them.
How far back does the data go?
Steam daily price history runs back to Apr 2013, and per-item daily price points are archived without a retention cutoff.
How do I filter for this provider only?
Use the repeated providers=steam parameter on supported list endpoints such as prices, bids, and sales. Raw price history uses the singular provider=steam parameter.
