This is not our API. This repository is an independent, third-party profile of a company's publicly available API surface, maintained by API Evangelist. API Evangelist does not operate, host, resell, or support this company's APIs, and is not affiliated with or endorsed by the company unless stated on the profile.
Where the information came from. Everything here is assembled from material a member of the public can reach with a browser and no credentials — the company's own website, developer portal and documentation, the specifications it publishes for public use (OpenAPI, AsyncAPI, JSON Schema,
apis.json,llms.txtand similar), its public repositories, and its public status, pricing and changelog pages. Nothing here is obtained by breaching a system, defeating an access control, or using credentials of any kind.The rating is an independent assessment. The Kin Score and Agent Readiness rating are independently calculated scores of a company's public API artifacts, produced by API Evangelist against a published rubric. They are not certifications, endorsements, security assessments, or audits, and they score published artifacts — not the quality, safety, or security of the software.
Corrections, re-scores, and removal are free. No partnership, contract, or purchase is required, and you do not need to justify the request.
- Something wrong? Open an issue on this repository, or email info@apievangelist.com.
- Published something new? Ask for a re-score and we will re-run the rating.
- Want the listing taken down? Say so and we will honor it. The profile is reduced to your company name, a factual description, and a link to your own site, and the company is recorded as unrated — never scored zero for having asked.
Response times. Acknowledgement within one business day; removal or restriction within two business days; corrections and re-scores within five business days.
On a security or compliance team? Email info@apievangelist.com with security in the subject line and you will get a person, not a form. We will tell you exactly which public URLs this profile was built from so your team can see the same surface we did, and we will take the listing down on request while you work through it.
Full detail: Where this data comes from
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 Online Services is Epic's free cross-platform backend for games. EOS exposes both a native C/C++ SDK (with Unity, Unreal, and platform wrappers) and a set of REST web services covering identity (Epic Account Services, Connect, Auth), social (Friends, Presence, Blocklist), play (Lobby, Sessions, P2P, Voice), progression (Achievements, Stats, Leaderboards), storage (Player Data Storage, Title Storage), integrity (Anti-Cheat, Sanctions, Reports), and commerce (Ecom). All EOS APIs are gated behind an Epic developer organization, sandbox, and client credentials issued in the EOS Developer Portal.

The Epic Games Store publishing surface lets developers upload builds, configure store pages, manage offers, run sales, and integrate with EOS achievements and entitlements. Publishing tools include the BuildPatchTool / EOS SDK Tool for uploading builds and a developer portal for managing products. There is no fully self-serve public REST Store API; publishing is gated through Epic's onboarding.
