Alliant Credit Union

Alliant Credit Union is a federally chartered, member-owned credit union headquartered in Chicago, Illinois, regulated by the National Credit Union Administration (NCUA). Founded in 1935 as the United Airlines Employees' Credit Union and rebranded Alliant in 2003, it is one of the largest credit unions in the United States, with more than 800,000 members and over $19 billion in assets. Alliant operates as a digital-first, branchless institution offering consumer and commercial deposit accounts, high-yield savings and checking, credit cards, auto and home loans, and business banking. Like nearly all U.S. credit unions, Alliant publishes no public first-party developer API or developer portal; consumer-permissioned data access is available to members only through third-party aggregators (Plaid, MX, Finicity, Akoya) rather than a directly documented open-finance API.

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

Alliant Credit Union’s developer surface includes engineering blog, support, and 4 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/.
