ClearBank

ClearBank is a UK clearing and Banking-as-a-Service bank, founded in 2015 by Nick Ogden (founder of WorldPay) and Charles McManus and granted a banking licence in December 2016 as the first new UK clearing bank in more than 250 years. ClearBank Limited is authorised by the Prudential Regulation Authority and regulated by the Financial Conduct Authority and the Prudential Regulation Authority (FRN 754568), with a European subsidiary, ClearBank Europe N.V., authorised by the European Central Bank. It is privately owned, backed by Apax Partners and PPF Group. Built cloud-native on Microsoft Azure, ClearBank is a direct participant in the UK payment schemes (Faster Payments, CHAPS, Bacs) and offers Agency Banking, Embedded Banking, and Transaction Banking to banks, fintechs, and corporates through a single proprietary JSON REST API. Unlike the CMA9 retail banks, ClearBank is not a mandated Open Banking ASPSP and does not publish the OBIE Open Data (ATMs/Branches/Products) or OBIE Read/Write (AISP/PISP/CBPII) APIs; its public developer surface is the token-authenticated, RSA-signed ClearBank Financial Institutions API covering GBP accounts and payments, multi-currency accounts, FX, SEPA, cross-border payments, Confirmation of Payee, customer due diligence (KYC), and embedded/retail banking, with a full simulation environment for onboarding.

ClearBank publishes 11 APIs on the APIs.io network, including GBP Accounts API, Faster Payments API, CHAPS API, and 8 more. Tagged areas include Financial-Services, Banking, Banking as a Service, Embedded Banking, and Payments.

The ClearBank catalog on APIs.io includes 1 event-driven AsyncAPI specification.

ClearBank’s developer surface includes authentication, sandbox, documentation, getting-started guide, API reference, engineering blog, and 37 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Banking & Open Finance regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.
The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.
Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/.
