buff
The cs2.sh BUFF163 API provides the most complete BUFF price data available. Real-time asks and buy orders, BUFF price history since 2023, real BUFF sale prices since September 6th, 2024, a price for every float range and fade range, and full support for Doppler and Case Hardened items. It returns ask, ask_volume, bid, and bid_volume for every CS2 item on /v1/prices/latest, collected every few minutes and normalized from CNY to USD. No Chinese account, BUFF session, proxy, or currency conversion is required.
/v1/prices/history returns continuously updating OHLC candles at 5m/30m/1h/1d for every BUFF item and variant, since December 24th, 2025. /v1/archive/history covers hourly and daily BUFF ask/bid prices and listing volumes back to 2023, alongside aggregate sale volume and total supply. /v1/archive/buff returns real BUFF sale prices and daily total supply since September 6th, 2024, per item and per variant. Together this is the best long-term BUFF price history available: three years of hourly listing prices and two years of real sale prices in one API.
Doppler phases, Gamma Doppler phases, and Case Hardened tiers are priced individually with their own ask, ask_volume, bid, and bid_volume. BUFF is the only source that prices by float range and fade range: /v1/market/buff/latest returns ask, avg_ask, bid, ask_volume, and bid_volume for every range on every item and variant, and /v1/market/buff/history keeps OHLC for every range at 30m/1h/1d since May 19th, 2026.
Every response is JSON keyed by the canonical market_hash_name, with updated_at and collected_at timestamps on every price. GET returns the whole market in one call; POST returns specific items. The same key and schema cover Youpin, CSFloat, Steam, Skinport, and C5Game.
About BUFF163: buff.163.com is China's NetEase-run, peer-to-peer CS2 marketplace, second-largest by volume and the baseline most of the market prices against. It is also the hardest source to collect: sessions are invalidated, IPs are blocked, and the only official API costs $150/month and is limited to Chinese accounts.

common questions
How often does cs2.sh update BUFF163 prices?
Every few minutes. cs2.sh collects BUFF listing prices, buy orders, volumes, and float and fade range prices for every item and variant every few minutes and normalizes them from CNY to USD. BUFF sale history updates daily.
How far back does BUFF price history go?
To 2023 for prices and to September 6th, 2024 for sales. /v1/prices/history has OHLC candles at 5m/30m/1h/1d since December 24th, 2025, /v1/archive/history has hourly and daily BUFF ask/bid prices and listing volumes back to 2023, /v1/archive/buff has real BUFF sale prices and daily total supply since September 6th, 2024, and /v1/market/buff/history has float and fade range history since May 19th, 2026.
Does the BUFF API include sale history?
Yes. /v1/archive/buff returns real BUFF sale prices and daily total supply for every item with sales on BUFF, including Doppler, Gamma Doppler, and Case Hardened variants, since September 6th, 2024. Points are BUFF sales, so recent history is spaced hours apart and older history days apart, and a point exists only where a sale happened.
Does the BUFF API cover Doppler and Case Hardened variants?
Yes. Doppler phases, Gamma Doppler phases, and Case Hardened tiers are priced individually with their own ask, ask_volume, bid, and bid_volume, not collapsed into one number. OHLC history, BUFF sale history, and float and fade ranges are returned per variant as well.
