YouPin API for CS2
Query YouPin898 listings, buy orders, and completed sales through one CS2Cap endpoint. Rather than integrating YouPin898 directly, you get its feed normalized alongside every other marketplace we track.
YouPin898 (悠悠有品) is the other half of the Chinese CS2 market alongside Buff163, and on many items it is the deeper book of the two. Its prices frequently diverge from Western marketplaces, which makes it the single most useful comparison point for anyone measuring true arbitrage rather than fee noise. It reports buy orders and completed sales as well as asks, so it can be read for demand and not just for price.
CS2Cap tracks 6.5M Youpin898 listings across 28.4K items, 67.5% of the CS2 catalog, holding $132.6M in listed value. That makes it the largest listing book of the 41 marketplaces tracked here. The feed refreshes every 10 minutes, with buy orders and completed sales. Prices are quoted in CNY and converted to USD with hourly-refreshed exchange rates. Daily Youpin898 price history runs back to Dec 2022.

Questions
Before you build
Is this an official YouPin898 API?
No. CS2Cap is a third-party aggregation service. YouPin898 data is included as one of many supported marketplace sources.
What data is available from YouPin898?
CS2Cap returns YouPin898 listing prices, buy orders, and individual sale records, refreshed every 10 minutes, with daily history since Dec 2022.
Is YouPin898 the same as YouPin, UU898, UU?
Yes. YouPin898 is also written as YouPin, UU898, UU, 悠悠有品. Those names all refer to the same marketplace, and this page covers that single feed.
Are Doppler phases and float values priced separately?
Doppler and Gamma Doppler phases are separate price entries on the YouPin898 feed. Individual float values and paint patterns are not separate price points; float value and paint seed appear on sale records where the marketplace publishes them.
How are CNY prices converted?
YouPin898 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=youpin parameter on supported list endpoints such as prices, bids, and sales. Raw price history uses the singular provider=youpin parameter.
