Built for price-aware products

SteamDeals is a multi-region data platform for storefronts, community applications, publishers, and analytics teams. Every offer is bound to a canonical game, store, region, currency, and observation time. The Deals Engine evaluates price history and store policy before an offer is published as a deal.

Quick start

  1. Create an API key in the Developer Console and keep it server-side.
  2. Request games with a region and currency context.
  3. Use lowest_price and best_deal to surface a current buying decision.
curl "https://api.steamdeals.example/v1/games?query=Hades&region=US" \
  -H "Authorization: Bearer sd_live_01HZX9JQX6Y7Q8"

{"data":[{"id":"game_01J2M4T5K7HADES2","name":"Hades II","lowest_price":{"amount":"20.99","currency":"USD","store_id":"store_steam"}}],"meta":{"request_id":"req_01J3KZ6VPG8J","next_cursor":null}}

Use webhooks for durable workflows

Use WebSocket for immediate UI updates. For notification workflows, exports, and database synchronization, configure webhooks, which are retried and signed.
