The BUFF163 price API from cs2.sh provides real-time and historical CS2 item prices, buy orders, and trade volume from BUFF163 (buff.163.com). BUFF is the second-largest CS2 marketplace by volume – a peer-to-peer platform operated by NetEase in China – and its prices are widely used as the reference baseline for item value.
cs2.sh collects BUFF prices every few minutes: listing prices, buy orders, and volume for all items. Prices are normalized from CNY to USD. Variant items (Doppler phases, Gamma Doppler, Case Hardened tiers) are fully supported with per-variant pricing.
BUFF is also the only marketplace where cs2.sh exposes float ranges and fade ranges per item, plus per-variant ranges for Doppler phases and Case Hardened tiers.
