ClearBank, UK‘s first clearing bank in 250 years, offers an API for banking

Three years in development, ClearBank has forged a partnership with the Bank of England [1] to set ClearBank up as UK’s fifth clearing bank, joining the ranks of the Big Four — Barclays, HSBC, Lloyds, and RBS [2].

ClearBank is not consumer-facing but instead offers an API [3] for its core banking platform.
