description: >-
  Ordnance Survey runs OAuth 2.0 as a bare client-credentials token service and
  publishes NO named scopes. The OS OAuth 2 API documentation describes only
  grant_type=client_credentials against https://api.os.uk/oauth2/token/v1 with
  HTTP Basic (Project API Key : Project API Secret), returning access_token /
  expires_in / issued_at / token_type. Authorisation is carried by which APIs
  are attached to the OS Data Hub API Project, not by scope strings - so a
  token that is refused returns 403 (not entitled) rather than an
  insufficient_scope error. The single scope below is the literal "read" scope
  declared in the operation security requirements of the OS Linked Identifiers
  OpenAPI fragments; it is not documented anywhere in prose and no other OS
  spec declares it.
