How to Get CS2 Sale Volume and Supply Data

A skin can show count: 500 listings and zero sales today — still liquid-looking but stale. Conversely, sales can spike while listings drop (inventory absorbed).

curl -s -X POST "https://api.cspriceapi.com/v1/prices/latest" \
  -H "x-api-key: YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"items":["AK-47 | Redline (Field-Tested)"],"markets":["youpin","buff163","skinport","csfloat","market-csgo"]}'

Use count to:

• Filter bots (count >= 10)
• Weight fair value confidence
• Spot fake arbs (1 listing at weird price)

Market.CSGO is notable for sales-count fields on listings where available — see Market.CSGO API.

• Detect manipulation (low sales at inflated ask)
• Build volume dashboards

YouPin898 is one of the main Chinese CS2 marketplaces. When measuring "market activity":

1. Start with YouPin + BUFF listing counts and YouPin sales (sales data covers YouPin, CSFloat and Skinport only).
2. Add Western markets for retail layer.
3. Report per-market — do not sum CNY and USD counts without conversion context.

DMarket "cheapest" ask is one listing — not a liquid market. A volume-aware bot skips count < 5.

• Rising listings + falling sales → supply glut, bearish
• Falling listings + rising sales → absorption, bullish
• Requires time series — combine daily history + daily sales aggregates
