  JSONPlaceholder is a free public service backed by the open-source json-server
  project. There is no commercial pricing surface, no signup, no paid tiers,
  and no metered usage. The service is offered as-is, with no SLAs, and is
  funded as a community project by typicode. Teams that need persistence,
  authentication, or contractual guarantees are expected to self-host
  json-server (or use typicode's My JSON Server) rather than purchase a tier
  on jsonplaceholder.typicode.com.
