Ask HN: Roles as Endpoints or Scoped Roles for an API?

Hi, I'm creating an API and wanting some suggestions or feedback on how roles should be addressed. Currently the system has four roles (responder, dispatcher, regionaladmin, admin). They all have access to only specific portions of the API.

Example of Roles as Endpoints:

Responders can get events (assigned to them) but not post.

  GET  /v1/responders/events

Dispatchers can get and post events

  GET  /v1/dispatchers/events
  POST /v1/dispatchers/events

Example of Scoped Roles:

  GET  /v1/events
  POST /v1/events

JSON Web Token with Scopes:

  Dispatcher
    {scopes: [events:read, events:create]}

  Responder
    {scopes: [events:read]}

Which one of these would be better or more flexible?
