  Apple CloudKit is the cloud backend for iOS, iPadOS, macOS, tvOS,
  watchOS, visionOS, and the web. CloudKit Web Services is the public REST
  surface that lets non-Apple-platform clients (web apps, servers) read
  and write data into a CloudKit container's public, private, or shared
  database. The web service is hosted at api.apple-cloudkit.com and accepts
  either an API token (for end-user-authenticated access) or a server-to-
  server ECDSA key for backend access. Operations cover records,
  zones, subscriptions, assets, users, and database changes.

      The CloudKit Web Services REST API is structured as
      /database/1/{container}/{environment}/{database}/{operation}, where
      database is one of public, private, or shared and environment is
      development or production. Operations include records lookup, query,
      modify, delete, zone create/list/delete, subscription
      create/list/delete, asset upload, user info and changes. Calls are
      authenticated using an API token for user-authenticated access (with
      ckWebAuthToken) or a server-to-server ECDSA key for backend access.
