common questions

What is cs2.sh?

cs2.sh is the leading price API for the Counter-Strike 2 skin market. We cover six marketplaces (BUFF, Youpin, CSFloat, Skinport, Steam, and C5Game) with the best real-time prices available and complete price and sale history: full bid/ask prices updated every ~5 minutes, OHLC price history at 5m to 1d intervals, full-depth Steam orderbooks, BUFF float and fade ranges, and sale history archives going back to 2013.

What makes cs2.sh different from other CS2 skin price APIs?

cs2.sh is the only CS2 price API that returns both the lowest listing and the highest buy order for all major marketplaces, updated every ~5 minutes, with high-frequency price history and real sale history behind every price.

  • Full bid/ask prices for all marketplaces, updated every ~5 minutes - both the lowest listing (ask) and the highest buy order (bid), with listing and order counts
  • Native support for variant items - Doppler, Gamma Doppler, and Case Hardened variants priced individually on every endpoint, including per-phase buy orders
  • High-frequency historical data - continuously updating OHLC candles at 5-minute to daily intervals for every item
  • 3+ years of archive data - bid/ask prices, sale volume, and item supply, daily and hourly
  • Long-term BUFF, Youpin, CSFloat, and Steam Community Market sale price & sale volume history for real sales, back to 2013 on Steam
  • Dedicated marketplace data - BUFF float and fade ranges and full-depth Steam bid/ask orderbooks
How far back does historical data go?

Up to 13 years, depending on the endpoint. High-frequency OHLC history at 5m/30m/1h/1d intervals goes back to December 24, 2025. Archive data - bid/ask prices, sale volume, and item supply - goes back to 2023 at hourly and daily resolution. The marketplace sale archives go back further: CSFloat daily sale prices and volume go back to 2022, BUFF sale prices and total supply go back to September 6, 2024, Youpin sale prices go back to November 12, 2025, and Steam Community Market median sale prices and volume go back to April 26, 2013, into the CS:GO era.

BUFF float and fade range history goes back to May 19, 2026, and full-depth Steam orderbook snapshots go back to June 9, 2026. Each interval has a maximum range per request - for example 14 days at 5m and 90 days at 30m - and longer exports combine several requests.

Does cs2.sh have Doppler phase prices?

Yes. Doppler (Phase 1-4, Ruby, Sapphire, Black Pearl), Gamma Doppler (Phase 1-4, Emerald), and Case Hardened (Tier 1-4, Blue Gem) are priced individually per marketplace on every endpoint, including price history and the sale history.
