Buff163 API for CS2

Query Buff163 listings, buy orders, and completed sales through one CS2Cap endpoint. Rather than integrating Buff163 directly, you get its feed normalized alongside every other marketplace we track.

Buff163 is the largest CS2 marketplace by traded value and the reference price for most of the market: when traders argue about what a skin is 'really' worth, they usually mean the Buff163 listing price. It is a Chinese platform with its own currency and account requirements, which puts it out of reach for many buyers even though its prices set the global baseline. That combination, indispensable pricing paired with awkward direct access, is why it is the most requested feed on CS2Cap.

CS2Cap tracks 3.5M BUFF163 listings across 32.9K items, 77.9% of the CS2 catalog, holding $99.6M in listed value. That makes it the 2nd-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 BUFF163 price history runs back to Jul 2021.
