  anonymously. The untouched export is in openapi/_original/barclays-authentication-openapi.json. The UK Open Banking documents
  carry OBIE (openbanking.org.uk) in info.contact/termsOfService because they are the OBIE standard contract as Barclays implements
  and publishes it — the API, the registry record and the host are Barclays'.
