Kongregate is a browser-game platform and publisher that hosts thousands of free online games across action, puzzle, RPG, strategy, idle and multiplayer genres. For game developers it operates a two-part developer API: a CDN-delivered client JavaScript API (with Unity WebGL bindings) handling player identity, in-page registration, statistic submission and the Kreds purchase flow; and a server-side REST API at api.kongregate.com that authenticates players, reads and consumes the Kreds virtual-goods inventory, submits statistics, reads lifetime/weekly/daily/friends leaderboards, and registers game-defined guilds and characters. Kongregate monetizes through Kreds, its own virtual currency, and rewards player engagement with badges and collectible Kongpanions. Outbound API callbacks are delivered as HMAC-SHA256 signed requests. Kongregate Inc. is backed by Lightspeed Venture Partners and Uncork Capital.
