  • Sort by price, listing volume, or recency.
  • Same DTO across REST and WebSocket streams.

# curl with API key
curl -H "X-Api-Key: $KEY" "https://www.steamwebapi.com/steam/api/items?markets=csdeals&game=cs2"
# PHP
$client = \Symfony\Component\HttpClient\HttpClient::create();
$res = $client->request('GET', 'https://www.steamwebapi.com/steam/api/items?markets=csdeals&game=cs2', ['headers' => ['X-Api-Key' => $KEY]]);
$items = $res->toArray();
# Node.js / JavaScript

About CS.DEALS

CS.DEALS 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 CS.DEALS 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.
