BECU

BECU (Boeing Employees' Credit Union) is a member-owned, not-for-profit state-chartered credit union founded in 1935 and headquartered in Tukwila, Washington (NMLS ID 490518). Originally serving Boeing employees, it is today one of the largest credit unions in the United States, offering consumer and business deposit accounts, lending, mortgages, and investment services across the Pacific Northwest and nationally through digital channels. Like the vast majority of US credit unions, BECU exposes no public first-party developer API or developer portal; its digital banking runs on established core and fintech vendors (FIS, LPL/Client Point, ICE/Ellie Mae for mortgage), and consumer-permissioned data access for third-party fintech apps is intermediated through data aggregators rather than a documented, self-serve BECU API. US open finance is voluntary and fragmented, and no mandated open-banking API contract applies here; the CFPB Section 1033 Personal Financial Data Rights rule is the emerging framework that will shape BECU's future data-access posture.

BECU is profiled on the APIs.io network. Tagged areas include Financial-Services, Banking, United States, Credit Union, and Open Finance.

BECU’s developer surface includes support, engineering blog, and 5 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 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/becu: open an issue to ask a question, or submit a pull request to add artifacts.
