BankUnited

BankUnited, N.A. is a national bank (OCC-chartered National Association) and the principal subsidiary of BankUnited, Inc. (NYSE: BKU), a bank holding company headquartered in Miami Lakes, Florida. With roughly $35 billion in total assets and banking centers across Florida, the New York metro area, Dallas, Atlanta, New Jersey and North Carolina, it is a mid-size regional commercial and consumer bank focused on business banking, commercial lending and treasury/depository services. On the open-finance front, BankUnited runs a first-party developer portal branded the "API Experience Hub" (developer.bankunited.com), a Salesforce Experience Cloud site fronting a MuleSoft Anypoint Exchange catalog with self-service registration, OAuth application provisioning and API contracts; the specific API products and any OpenAPI specifications sit behind portal registration/login rather than being openly downloadable. No FDX-conformant public data-access API or published CFPB Section 1033 posture is documented; consumer-permissioned account data is reached primarily through third-party aggregators (e.g. Plaid) rather than a public first-party consumer data API.

BankUnited publishes 1 API on the APIs.io network. Tagged areas include Financial-Services, Banking, United States, Regional Bank, and Commercial Banking.

BankUnited’s developer surface includes authentication, signup flow, developer portal, engineering blog, and 13 more developer resources.

Kin Score Kin Score How this is scored →
scored 2026-09-08 · rubric v0.20.0
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 could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.
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/bankunited: open an issue to ask a question, or submit a pull request to add artifacts.
