Metro Bank

Metro Bank is a UK retail and commercial bank founded in 2010 as the first new high-street bank to open in Britain in over 150 years, headquartered in London and listed on the London Stock Exchange (ticker MTRO). It is a public limited company (not a mutual or building society), authorised by the Prudential Regulation Authority and regulated by the Financial Conduct Authority and the PRA, serving personal and business customers through its branch ("store") network and digital channels. As an FCA-authorised account servicing payment service provider (ASPSP) under PSD2, Metro Bank participates in UK Open Banking without being one of the nine CMA-mandated banks (the CMA9). It operates a public developer portal, built on Google Apigee, that publishes PSD2 / UK Open Banking APIs aligned to the Open Banking Implementation Entity (OBIE) Read/Write standard - Account and Transaction Information, Payment Initiation, and Confirmation of Funds - secured with FAPI-grade OAuth2/OIDC, mutual TLS, dynamic client registration, and PSD2 strong customer authentication, alongside the OBIE Open Data reference-data APIs and FCA service-quality metrics reporting.

Metro Bank publishes 6 APIs on the APIs.io network, including ATM API, BCA API, Branch API, and 3 more. Tagged areas include Financial-Services, Banking, Open Banking, PSD2, and OBIE.

Metro Bank’s developer surface includes authentication, documentation, engineering blog, support, and 18 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.

Create-or-Update Ergonomics does not apply to this provider. The published contracts declare no write operations, and a read-only API cannot create-or-update. The facet is excluded from this provider's denominator entirely — not scored zero. A reference or data API is not deficient for being unable to upsert.

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/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/metro-bank: open an issue to ask a question, or submit a pull request to add artifacts.
