Introduction

On this page

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, Gamma Doppler, Case Hardened, and other variant items on all endpoints
3+ years of archive price data - for bid/ask prices, sale volume, and item supply
Long-term BUFF, Youpin, CSFloat, and Steam Community Market sale price & sale volume history (~13 years of data depending on source)

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.

In short, cs2.sh is built with care and a focus on quality. If that's something you value, too, you'll probably like the API :).
