How to Get CSFloat Buy-Order Prices

CSFloat's site shows both sides. API users typically:

1. Poll CSFloat asks for Western listing arb.
2. Poll YouPin buy orders for CN exit / cash-out modeling.
3. Match (market_hash_name, doppler_phase) on both.

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

Response includes CSFloat lowest ask in USD and YouPin ask in CNY.

Full buy-side depth — use for "sell now" valuation:

curl -s "https://api.cspriceapi.com/v1/prices/youpin/buyorder" \
  -H "Authorization: Bearer YOUR_API_KEY"

Join to listings:

# Pseudocode: key = (market_hash_name, doppler_phase or None)
asks = index_latest(post_latest(..., markets="csfloat,youpin"))
bids = index_buyorder(get_youpin_buyorder())
spread = asks["youpin"].price - bids["youpin"].top_bid  # CNY, same item

Exact field names: see OpenAPI and buyorder docs.

Many CSFloat sellers source from Chinese wholesale (YouPin/BUFF). Profit math:

net_usd = csfloat_ask * (1 - csfloat_fee) - youpin_cost_usd - withdrawal_fx_cost

Sell-now uses youpin_buyorder top bid, not YouPin listing ask — the spread between ask and bid is real money.

Buy orders for Doppler knives are phase-specific on YouPin. A bid on Phase 3 does not apply to Ruby.

Always filter:

market_hash_name == "★ Karambit | Doppler (Factory New)"
AND doppler_phase == "Ruby"

See Doppler guide.

On CSFloat.com, buyers can post orders conditioned on float, pattern, stickers. Site-level detail may exceed generic API rows. Use CSPriceAPI for market-wide phase and commodity pricing; use CSFloat UI or specialized tools for one-off crafts.

For float buckets across markets:

curl -s "https://api.cspriceapi.com/v2/prices/float-ranged?market=csfloat" \
  -H "Authorization: Bearer YOUR_API_KEY"

CSFloat listing history:

curl -s "https://api.cspriceapi.com/v1/prices/csfloat/history?market_hash_name=AK-47%20%7C%20Redline%20(Field-Tested)" \
  -H "Authorization: Bearer YOUR_API_KEY"

YouPin daily history for bid/ask context over time:

curl -s "https://api.cspriceapi.com/v1/prices/youpin/history?market_hash_name=AK-47%20%7C%20Redline%20(Field-Tested)" \
  -H "Authorization: Bearer YOUR_API_KEY"

AK-47 | Redline (Field-Tested) on YouPin:

Spread = ¥7 (~4.8%). A trader "selling now" to bid gets ¥138, not ¥145. Inventory tools should store both (valuation guide).
