OBIE Account & Transaction Information API (AIS - Standard, Out of Scope)
The OBIE Read/Write Account and Transaction Information (AISP) standard for reading account, balance and transaction data. FAPI-secured with OAuth2/OIDC, mutual-TLS and PSD2 strong customer authentication. Represented here as the documented OBIE standard only - Principality offers no current or payment accounts, publishes no ASPSP developer portal, and is therefore OUTSIDE the scope of this Read/Write API. No Principality base URL or credentials exist; none are invented.
