Fourth Dimension Operating System (4D OS) is a platform that provides organizations with a comprehensive set of tools to manage fan engagement, loyalty, rewards, consent, and more. Your organization brings its members; 4D gives you one place to hold their identity, track how they engage, reward that engagement with XP, and respect their consent choices throughout - with an on-chain XP token settling behind the scenes. You integrate through our REST API, authenticated with an organization API key, and there is a lightweight engagement SDK for browser event tracking. Everything your key touches is scoped to your organization: your members, your events, your XP economy.

​
The pieces

  • Tenants and members - your organization is a tenant; each person in your member base is a member of it. One person can hold a single 4D identity across many organizations. See Tenants and members.
  • Events - engagement events flow in from your sites and apps (a publishable tracking key, batched browser events) and drive everything downstream. See Events.
  • XP - a double-entry loyalty ledger. Rules turn events into XP awards; tiers rank members; balances settle to an on-chain token. See XP.
  • Consent - append-only consent records gate what the platform does with member data. See Consent.

API reference

The API reference is generated live from the same schemas the server validates against, so it cannot drift from what the API actually accepts.
