TSB Open Data API
TSB's public, unauthenticated Open Data API conformant to the OBIE Open Data API Standard, exposing reference data for ATMs, branches, personal current accounts, business current accounts, unsecured SME loans, and commercial credit cards. No live TSB Open Data endpoint was confirmed at review time; the harvested OpenAPI is the shared OBIE Open Data standard, not a TSB proprietary contract.
