The Co-operative Bank

The Co-operative Bank plc is a UK high-street retail and commercial bank, headquartered in Manchester and long known for its customer-led ethical banking policy.

Authorised by the PRA and regulated by the FCA and PRA, it is an FCA-authorised ASPSP under PSD2 and the UK Open Banking regime. While it is not one of the nine CMA-mandated banks (CMA9), it implements the Open Banking Implementation Entity (OBIE) Read/Write API Standard (v3.1) and publishes a public developer portal at developer.co-operativebank.co.uk exposing Account Information (AIS), Payment Initiation (PIS), and Confirmation of Funds (CBPII) APIs for both the Co-operative Bank and smile brands, secured with FAPI-grade OAuth2/OIDC, mutual-TLS client authentication using Open Banking directory certificates, and PSD2 strong customer authentication, with a manual TPP onboarding process and a sandbox for testing before production.

The Co-operative Bank publishes 1 API on the APIs.io network: Open Data API (OBIE standard). Tagged areas include Financial-Services, Banking, Open Banking, PSD2, and OBIE.

The Co-operative Bank’s developer surface includes documentation, getting-started guide, authentication, sandbox, support, signup flow, and 21 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/.
