CS2 Skin Prices - Steam vs Skinport Spread, No API Key

Compares the price of Counter-Strike 2 skins on the Steam Community Market and Skinport, with volume and the spread after fees. For skin traders, bot builders and analysts who do not want to pay $100+/month for a price API.

It calls the public Skinport API and Steam's priceoverview endpoint, throttled to Steam's roughly 20 requests per minute limit. No API key, no login, no browser.

Input examples

Check the skins you hold or watch:

{ "items": ["AK-47 | Redline (Field-Tested)", "AWP | Asiimov (Field-Tested)"], "currency": "USD" }

Find worthwhile gaps only (net +5% or more after fees, at least 20 Steam sales yesterday):

{ "maxItems": 40, "minItemPrice": 10, "maxItemPrice": 150, "minSpreadPct": 5, "minSteamVolume": 20 }

Euro prices, your own fee assumptions:

{ "items": ["M4A4 | Desolate Space (Field-Tested)"], "currency": "EUR", "skinportFeePct": 8, "steamFeePct": 15 }

{} works: it picks 12 liquid weapon skins from Skinport and prices them on Steam (about 40 seconds).

FAQ

Why is the spread so large? Steam Market money is wallet credit that can only buy things on Steam, so Steam listings carry a premium over cash markets like Skinport. walletToCashSpreadPct is real only if you value wallet credit at face value. cashToCashSpreadPct is the one that matters if you want cash out.

Are the fees exact? No. Fees are assumptions you can change. Steam also has minimum fees on very cheap items, and Skinport's fee depends on your seller tier. Payment-method fees at checkout are not included.

What if Steam blocks the run? Steam rate-limits hard. If it keeps answering 429 after two waits, the remaining items are returned as type: "partial" rows with Skinport data only (free). Raise steamDelayMs or enable the proxy.

Honest limits

• Prices are snapshots; listings move in seconds. This is research data, not a trading guarantee.
• Steam allows about 20 lookups per minute, so large lists take a while (100 items is about 5-6 minutes).
• Only CS2 (appid 730). Float, pattern and sticker values are not considered; "lowest price" is the cheapest listing of any float.
• Skinport and Steam can change or restrict their endpoints at any time.

Price

Pay per event: item-priced $0.0005 per item with both a Steam and a Skinport price. Example: 100 items = $0.05. Error rows and Skinport-only partial rows are free.
