Epic Games is the studio behind Fortnite, the Unreal Engine, the Epic Games Store, MetaHuman, RealityScan, Twinmotion, RAD Game Tools, and the Epic Online Services (EOS) backend. Epic operates a unified developer portal at dev.epicgames.com that hosts the EOS SDK and REST APIs (Auth, Connect, Friends, Presence, Lobby, Sessions, Achievements, Stats, Leaderboards, Player Data Storage, Title Storage, Voice, Sanctions, Anti-Cheat, Reports, P2P, Ecom, User Info), the Unreal Engine documentation, the Epic Games Store publishing tools, and the Kids Web Services (KWS) compliance platform. EOS is cross-platform and runs on Windows, macOS, Linux, PlayStation, Xbox, Switch, iOS, Android, and web. This profile rolls Epic's developer-facing surfaces into a single index; the Unreal Engine surface has its own dedicated profile.
Epic Games publishes 9 APIs on the APIs.io network, including Achievements API, Auth API, Connect API, and 6 more. Tagged areas include Achievements, Anti-Cheat, Cross-Platform, EOS, and Epic Online Services.
Epic Games’ developer surface includes authentication, developer portal, documentation, API reference, getting-started guide, status page, support, and 19 more developer resources.
Create-or-Update Ergonomics applies to this provider. This API accepts writes, so it
carries 10 points of the composite. It is scored from the published contracts
themselves: whether a caller can create-or-update in one call, whether the write accepts a key the caller already
holds, and whether the response says which branch ran. Without that, every write needs a search-and-branch in
front of it, and the first time that check is skipped a duplicate record is created.
Scored against the observed mean rather than raw — a provider at the catalog average is unchanged by this facet,
not penalised by it.
Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/epic-games: open an issue to ask a question, or submit a pull request to add artifacts.
