C5Game API

Long-running Chinese marketplace, quoted in CNY and converted to USD. Get C5Game's lowest ask and listing count for 13,425 CS2 items, refreshed every 10 minutes — in the same response as Steam and 7 other marketplaces. Grab a free key or read the docs.

Why read C5Game through this API

C5Game rounds out the Chinese picture: together with Buff163 and YouPin898 it shows where CS2 skins actually clear in the largest skin market in the world.

C5Game prices arrive in yuan and are converted with daily ECB reference rates. It is read on the same ten-minute cycle as the other Chinese venues, so the three are always directly comparable.

The point of a single API is that you are not maintaining 8 integrations. C5Game 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 C5Game 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 9 sources, computed for you.
• Your currency — 30+ currencies via daily ECB reference rates.

Example: C5Game 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": 2871 },
  "spread": 297,
  "markets": [
    { "market": "csfloat", "price": 2871, "quantity": 3450, "capturedAt": "2026-07-30T11:40:02Z" },
    { "market": "buff163", "price": 2871, "quantity": 10589, "capturedAt": "2026-07-30T11:40:06Z" },
    { "market": "youpin", "price": 2926, "quantity": 10000, "capturedAt": "2026-07-30T11:40:06Z" },
    { "market": "c5game", "price": 2971, "quantity": 2428, "capturedAt": "2026-07-30T11:40:06Z" },
    { "market": "skinport", "price": 3015, "quantity": 559, "capturedAt": "2026-07-30T11:40:06Z" }
  ]
}

At build time C5Game was asking $29.71 for that item with 2,428 listings, against $28.71 at the cheapest venue (csfloat). That gap is exactly what the best and spread fields hand you without comparing anything yourself.

Tracking C5Game 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 C5Game's own history and compare it against Steam's median-sale series — which reaches back to 2013-08-13 and totals 15,581,753 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. C5Game'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 C5Game 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 C5Game 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();

C5Game 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: 29,458 CS2 and 5,397 Rust items carry a Steam ask, with median-sale history back to 2013 — 15,581,753 daily points in total.
