note: >-
  Derived from the shared OBIE Open Data API v1.3 reference specification carried
  in this repo, NOT a Principality-operated endpoint. The Open Data API is public
  reference data and defines no security schemes. The OBIE Read/Write APIs
  (AIS/PIS/CBPII) that Principality does NOT operate would, by the standard, use
  FAPI-secured OAuth2/OIDC + mutual-TLS + PSD2 SCA; that model is documented in
  the standard only and no Principality authorization server exists.
