Why read SkinBaron through this API

SkinBaron is the marketplace of record for the German-speaking skin scene, and its EUR-native asks give you the European price point directly — where the EU and US markets disagree, the gap shows up here first.

SkinBaron’s merchant API returns the whole catalog pre-aggregated in one response, including a separate row for every Doppler and Gamma Doppler phase. We read it every five minutes, convert EUR to USD with daily ECB reference rates, and store the lowest ask plus the listing count behind it.

The point of a single API is that you are not maintaining 11 integrations. SkinBaron arrives in the same shape as every other market: minor units, a currency, a listing count and a capture timestamp. Switch ?currency=EUR and every market converts together.

What you get for each SkinBaron item

• Lowest ask — the cheapest live listing, in integer minor units (no floats, no rounding drift).
• Listing count — how many listings sit behind that price, so you can tell a real floor from one lucky listing.
• Capture timestamp — when we last read it, per market. Never a silently stale number.
• Cross-market best — the cheapest venue for that item across all 12 sources, computed for you.
• Doppler phase prices — 262 phase-level quotes from SkinBaron.
• Your currency — 30+ currencies via daily ECB reference rates.

Example: SkinBaron in a cross-market response

One request returns every market's live price for an item. Prices below were true when this page was built:

curl "https://steamdataapi.com/api/v1/items/AK-47%20%7C%20Redline%20(Field-Tested)/markets" \
  -H "Authorization: Bearer sdk_YOUR_KEY"

{
  "currency": "USD",
  "best": { "market": "csfloat", "price": 2682 },
  "spread": 274,
  "markets": [
    { "market": "csfloat", "price": 2682, "quantity": 3759, "capturedAt": "2026-08-26T18:25:01Z" },
    { "market": "c5game", "price": 2777, "quantity": 2933, "capturedAt": "2026-08-26T18:20:21Z" },
    { "market": "youpin", "price": 2797, "quantity": 10000, "capturedAt": "2026-08-26T18:20:21Z" },
    { "market": "haloskins", "price": 2804, "quantity": 2412, "capturedAt": "2026-08-26T18:25:07Z" },
    { "market": "buff163", "price": 2818, "quantity": 10671, "capturedAt": "2026-08-26T18:20:21Z" }
  ]
}

At build time SkinBaron was asking $29.17 for that item with 110 listings, against $26.82 at the cheapest venue (csfloat). That gap is exactly what the best and spread fields hand you without comparing anything yourself.

Tracking SkinBaron prices over time

A single ask tells you today; a series tells you whether today is unusual. Every market accrues a daily lowest-ask point, so you can pull SkinBaron's own history and compare it against Steam's median-sale series — which reaches back to 2013-08-13 and totals 16,444,511 daily points across the catalog.

curl "https://steamdataapi.com/api/v1/items/AK-47%20%7C%20Redline%20(Field-Tested)/history?source=markets&days=90" \
  -H "Authorization: Bearer sdk_YOUR_KEY"

The two series answer different questions. Steam's median is what items actually sold for, which lags but cannot be moved by one optimistic listing. SkinBaron's daily low is what you could have bought at. Traders generally want both: the sale price to value a position, the ask to act on one.

From a SkinBaron price to a portfolio total

The same prices drive inventory valuation. Give the inventory endpoint a public SteamID and every item comes back priced — at the Steam ask and at cross-market real value, with SkinBaron included in the comparison — plus float, paint seed and Doppler phase where they apply, and a portfolio total in your currency.

const res = await fetch(
  "https://steamdataapi.com/api/v1/inventory/76561198000000000?game=cs2&currency=EUR",
  { headers: { Authorization: "Bearer sdk_YOUR_KEY" } },
);
const { totalValue, items } = await res.json();

SkinBaron versus the other markets we read

Item coverage differs a lot by venue. These counts are live from our own catalog:

Steam itself is the ninth source: 30,320 CS2 and 5,435 Rust items carry a Steam ask, with median-sale history back to 2013 — 16,444,511 daily points in total.
