Kroo
Kroo Bank Ltd is a UK app-based challenger bank, founded in 2016 and granted a full UK banking licence by the PRA/FCA in 2021 (restrictions lifted in 2022), that launched its digital-only personal current account in December 2022. Independent and venture-backed rather than mutual or part of a larger group, Kroo offers a fee-free everyday current account, interest-paying balances and "Kroo Pots", fee-free spending abroad, and FSCS deposit protection up to GBP 85,000. As an FCA-authorised ASPSP under PSD2, Kroo is a regulated Open Banking provider (though not one of the nine CMA9-mandated banks and, as a branchless digital bank, it publishes no Open Data reference APIs for ATMs or branches). It exposes the UK Open Banking Implementation Entity (OBIE) Read/Write API family - Account and Transaction Information, Payment Initiation, and Confirmation of Funds - through a Banfico-hosted developer portal at developer.kroo.banfico.io, secured with FAPI-grade OAuth2/OIDC, PSD2 strong customer authentication implemented as a CIBA decoupled (poll-mode) flow, and mutual-TLS client authentication using OBIE/eIDAS certificates, validated with the OpenID Foundation conformance suite.
Kroo publishes 28 APIs on the APIs.io network, including Account Access Consents API, Accounts API, Balances API, and 25 more. Tagged areas include Financial-Services, Banking, Open Banking, PSD2, and OBIE.
Kroo’s developer surface includes authentication, documentation, engineering blog, support, and 26 more developer resources.
