Eco Steam API for CS2
Query Eco Steam listings and buy orders through one CS2Cap endpoint. Rather than integrating Eco Steam directly, you get its feed normalized alongside every other marketplace we track.
ECOSteam is one of the larger Chinese venues by listing count, with a peer-to-peer book, buy orders, and no fee taken from sellers on listing. Its catalog coverage is comparable to the major Chinese marketplaces, which makes it a genuine third reading on the Chinese price level rather than a thin echo of it. Where it parts from Buff163 and YouPin898 is usually where regional supply is moving.
CS2Cap tracks 3.9M ECOSteam listings across 29.7K items, 70.5% of the CS2 catalog, holding $84.1M in listed value. That makes it the 4th-largest listing book of the 41 marketplaces tracked here. The feed refreshes every 5 minutes, with buy orders. Prices are quoted in CNY and converted to USD with hourly-refreshed exchange rates. Daily ECOSteam price history runs back to Apr 2026.

Questions
Before you build
Is this an official Eco Steam API?
No. CS2Cap is a third-party aggregation service. Eco Steam data is included as one of many supported marketplace sources.
What data is available from Eco Steam?
CS2Cap returns Eco Steam listing prices, buy orders, refreshed every 5 minutes, with daily history since Apr 2026.
Is Eco Steam the same as ECOsteam, ecosteam.cn?
Yes. Eco Steam is also written as ECOsteam, ecosteam.cn. Those names all refer to the same marketplace, and this page covers that single feed.
Are Doppler phases and float values priced separately?
No. Eco 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 are CNY prices converted?
Eco Steam quotes in CNY. CS2Cap stores the native price and converts at read time to USD, or the currency you request, using exchange rates refreshed hourly.
How do I filter for this provider only?
Use the repeated providers=ecosteam parameter on supported list endpoints such as prices, bids, and sales. Raw price history uses the singular provider=ecosteam parameter.
