## OpenAPI

openapi: 3.1.0
info:
  title: UserKit API
  version: 1.0.0
  description: >-
    The HTTP surface of UserKit.


    Two planes share one API. The **staff plane** is what a human uses in the
    panel: users, organizations, roles, members, keys. The **customer plane** is
    what a developer's own product uses: contacts, identities, hosted or
    federated sign-in.


    Every error answers the same envelope — `{"error": {"code", "message"}}`.
    The `code` is a stable contract to branch on; the `message` is for a person
    and may change.
