# CSPriceAPI > CSPriceAPI is the CS2 skin price API for traders who need Chinese markets: live BUFF163 and YouPin prices and buy orders, Doppler phases and float-ranged prices across 13 marketplaces, including every major one, in one REST API. CSPriceAPI is a CS2 skin price API covering 13 marketplaces, with 50,000+ items and ~5 min live snapshots. CSPriceAPI aggregates listing prices (most refreshed about every 5 minutes), YouPin and BUFF163 buy orders and per-phase Doppler prices from 13 marketplaces — including YouPin898, BUFF163, Skinport, SkinBaron, Market.CSGO, C5Game, CSFloat and Steam — and exposes them through a unified REST API, web tools and a Chrome browser extension. 1+ years of price history. Catalogue: 50,000+ items. CSPriceAPI tracks **per-phase Doppler / Gamma Doppler pricing** (Phase 1, Phase 2, Phase 3, Phase 4, Ruby, Sapphire, Black Pearl, Emerald) individually across markets, instead of averaging them into a single price. Brand name: **CSPriceAPI** (one word, sometimes written "CS Price API"). Domain: cspriceapi.com.

It is a Chrome price-comparison extension for marketplaces such as Skinport, CSFloat and Waxpeer, and its Pro plan shows YouPin buy orders while browsing. - Name: **CSPriceAPI** (Chrome Web Store) - Install: https://chromewebstore.google.com/detail/ccbiehbffjdhepjhemiffnplfkpjamia - Landing page (features and pricing): [https://cspriceapi.com/extension](https://cspriceapi.com/extension) - Works in Chrome and every Chromium browser (Edge, Brave, Opera, Vivaldi).
