How to Compare CS2 Skin Prices Across Marketplaces

Fetch all markets in one call, then join on identity:

curl -s "https://api.cspriceapi.com/v1/prices/latest?markets=youpin,buff163,skinport,csfloat" \
  -H "Authorization: Bearer YOUR_API_KEY"

Matching rules:

1. Same market_hash_name (exact string, including wear tier).
2. Same doppler_phase for Doppler / Gamma Doppler items — never compare Ruby against Phase 2.
3. Convert currencies before ROI: CNY (YouPin, BUFF), EUR (Skinport, SkinBaron), USD (CSFloat, Market.CSGO).

ROI example: buy on Skinport at €100, reference YouPin at ¥820 → convert ¥820 to EUR, subtract Skinport seller fee, compare net.

Price Comparison ranks skins by ROI between any two markets. Inputs: from-market, to-market, min price, min listing count, fee %, blacklist keywords. Output: ranked list with Doppler-aware matching.

Live Deals surfaces real-time cross-market gaps — when the same skin is materially cheaper on market A than B.

The CSPriceAPI extension overlays comparison prices directly on Skinport, CSFloat, Waxpeer and seven other marketplaces while you browse.
