Dedicated CSDeals 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.

GET /market/csdeals/prices

Live prices snapshot

Returns the current CSDeals catalogue as a flat array. Each row is one item with the lowest active price we have on record.

Sample response

[
  {
    "market_hash_name": "Souvenir UMP-45 | Gunsmoke (Minimal Wear)",
    "price": 130.69,
    "quantity": 1,
    "createdat": "2026-07-16T00:00:00+00:00",
    "variants": null
  },
  {
    "market_hash_name": "Sticker | Slab (Foil) | Krakow 2017",
    "price": 114.65,
    "quantity": 1,
    "createdat": "2026-07-16T00:00:00+00:00",
    "variants": null
  }
]

· 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.

GET /market/csdeals/history

Per-item price history

Daily-snapshot history of the lowest CSDeals price for a given item, ideal for charts and portfolio trackers.

Sample response

[
  {
    "createdat": "2026-07-09T00:00:00+00:00",
    "price": 124.40,
    "quantity": 1
  },
  {
    "createdat": "2026-07-15T00:00:00+00:00",
    "price": 130.69,
    "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 CSDeals

CSDeals is one of the third-party marketplaces aggregated by the Steamwebapi pricing layer. Listings are scraped on a fixed schedule, normalised into a single schema, and merged with the data we collect from Steam, other community markets, and direct exchange integrations.

If you build a portfolio tracker, an arbitrage bot, or simply need a reliable price reference for CSDeals items, you can hit the unified /steam/api/items endpoint with markets=csdeals instead of building one scraper per source.

For the complete list of supported marketplaces, refresh cadence, and an interactive playground, see our Price API hub.
