  title: Argus API
  version: 0.1.0
  summary: The HTTP API behind the Argus web application.
  description: >-
    Argus is the operations platform for the UK London Mayfair ER:LC community.
    This document describes the API its own web application uses.


    **This is an internal application API.** It is not a stable public API:
    paths, fields and behaviour can change with any release, there is no
    versioning, and browser requests are tied to the application's own origin.
    Scoped service credentials exist for the community's own integrations.


    All paths are relative to `/api` on the deployment's origin. Responses are
    JSON, never cacheable, and carry an `X-Request-Id` header.
servers:
  - url: http://localhost:3000/api
