How to Get Steam Community Market Prices for CS2 Items

CSPriceAPI is an independent aggregator, not an official Valve API. Steam has no public market API for third-party developers.

{
  "market": "steam",

  "updated_at": "2026-08-28T12:00:00Z",
  "items": [
    {
      "market_hash_name": "AK-47 | Redline (Field-Tested)",
      "price": 42.50,

  ]
}

Listing ≠ sale. Steam price is what sellers ask right now. A skin can sit listed for weeks without selling. Confirm with market sales search when sizing a trade.

Steam Wallet ≠ cash. Valve takes ~15% on sales and funds stay in Steam Wallet. A $150 Steam listing does not equal $150 bank cash. For cash valuation, weight YouPin898 or BUFF163 (CNY) and Western markets (EUR/USD).

Steam is slow to react. Skinport and YouPin often move first on meta shifts (tournament stickers, case drops). Steam lags — good for reference, risky as sole arb target.

Null is missing, not zero. If an item returns no row, it may have zero listings — do not substitute 0 in portfolio math.

International traders use this pattern daily:

1. YouPin898 sets the global wholesale reference (CNY).
2. BUFF163 tracks YouPin closely — gaps = CN arbitrage.
3. Skinport / CSFloat = Western cash venues (EUR/USD).
4. Steam = visibility and wallet-only liquidity.

Compare all four in one call:

curl -s -X POST "https://api.cspriceapi.com/v1/prices/latest" \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"items":["★ Karambit | Doppler (Factory New)"],"markets":"steam,youpin,buff163,skinport,csfloat"}'

Match rows by (market_hash_name, doppler_phase). A Karambit Doppler Ruby on CSFloat is not comparable to Phase 4 on Steam.

Suppose POST returns:

At ¥7.2 / USD, YouPin ≈ $389 cash-equivalent listing. Steam shows ~34% above the CN reference — common on liquid skins (Steam convenience premium). That gap is not free profit: you cannot withdraw Steam Wallet to bank at par.

Decision: A bot should not auto-buy on Skinport because Steam is higher unless it models wallet value separately.
