Query CSFloat via our API
Filter the unified /steam/api/items endpoint
with markets=csfloat to
return only CSFloat listings — or omit it for a side-by-side view across every marketplace.
- → Single auth header, same JSON schema for every market.
- → Filter by game, item name, price range, float.
- → Sort by price, listing volume, or recency.
- → Same DTO across REST and WebSocket streams.
Dedicated CSFloat endpoints
On top of the unified /steam/api/items route, every market we cover gets two convenience endpoints — one schema, one auth header, every marketplace.
/market/csfloat/prices
Live prices snapshot
Returns the current CSFloat catalogue as a flat array. Each row is one item with the lowest active price we have on record.

- · Same JSON schema across every marketplace we cover.
- · We surface the lowest price per item — never an average, never a stale tick.
- · Optionally filter by market_hash_name or convert prices via ?currency=EUR.
/market/csfloat/history
Per-item price history
Daily-snapshot history of the lowest CSFloat price for a given item, ideal for charts and portfolio trackers.

"price": 124.40,

{
"createdat": "2026-09-09T00:00:00+00:00",

"quantity": 1
}
]
- · One row per day, always the lowest price we recorded for that day.
- · Bounded with start_date and end_date (YYYY-MM-DD).
- · market_hash_name is required — history is per-item, not per-market.
Prefer one call across every marketplace? Use the unified /steam/api/items endpoint with markets=… — same DTO, comparison data included.
About CSFloat
CSFloat is one of the most trusted Western CS2 marketplaces, specifically designed around float values and sticker authenticity. If your application cares about the exact float of an item — for arbitrage, for portfolio tracking, or for showcasing low-float trophies — CSFloat is one of the few data sources that lets you query by float range natively.
Our API normalises CSFloat listings into the same JSON schema we use across every market we cover. You get the float value, the listing price, the seller, the stickers, and a side-by-side comparison against Buff, Skinport, DMarket and the rest. One key, one schema.
CSFloat API — FAQ
What is CSFloat?
CSFloat is a Western CS2 marketplace focused on float values and sticker authenticity. It's widely considered one of the most trustworthy P2P marketplaces in the CS2 ecosystem.
Which games does CSFloat support?
CSFloat is CS2-exclusive — it doesn't list other Steam games. Our API surfaces its full CS2 catalogue alongside the same items on Buff, Skinport and others.
Do I need a CSFloat API key to access CSFloat prices?
Use your Steamwebapi API key and call /steam/api/items with markets=csfloat. The Steamwebapi documentation describes the request and normalized response; this is separate from any credential issued directly by CSFloat.
How fresh are CSFloat prices?
We scrape CSFloat on a regular cadence — check the 'Last refresh' stat above for the most recent pull. Hot items refresh more often than the long tail.
Is CSFloat safe to use?
CSFloat is widely regarded as one of the safest P2P marketplaces in CS2. Still — verify directly with the marketplace before transacting. We surface CSFloat for data, not as a trading recommendation.
