# Introduction

High-frequency Counter-Strike 2 price history, current prices, liquidity, supply, and sale volume, with Doppler and Case Hardened variants priced individually.

cs2.sh is the leading price API for the Counter-Strike 2 skin market. We collect & provide the fastest, most comprehensive real-time and historical price data across all major marketplaces.

Unlike other APIs, cs2.sh is focused on giving you the *best* data across our supported marketplaces (Youpin, BUFF, CSFloat, Steam, Skinport, and C5Game). We provide:

- Full bid/ask prices, updated every ~5 minutes
- High-frequency historical data (5m - 1d intervals)
- Support for Doppler and variant items on all endpoints
- 3+ years of archive price data - for bid/ask prices, sale volume, and item supply
- Long-term Youpin, CSFloat, and Steam Community Market sale price & sale volume history

cs2.sh's goal is to provide the best price data and make it easy to build with - since it tends to be an integral part of a website, automated trading system, bot, or app. We handle all of the headaches that come with continuous, high-frequency data collection (we're at 30 billion+ events and counting) so that you can focus on building what matters to you.
