description: >-
  Zions Bancorporation, National Association is a nationally chartered bank and
  bank holding company headquartered in Salt Lake City, Utah, with roughly $87
  billion in total assets. It is a super-regional operating a single national
  bank charter across seven regional divisional brands - Zions Bank, Amegy Bank,
  California Bank & Trust, National Bank of Arizona, Nevada State Bank, Vectra
  Bank Colorado, and The Commerce Bank of Washington - serving consumers, small
  business, and commercial/treasury clients across the Western United States. On
  the open-finance front Zions runs NO public first-party developer API portal:
  developer.zionsbank.com and api.zionsbank.com do not resolve, and its business
  digital-banking surface (Treasury Internet Banking at treasurygateway.zionsbank.com)
  is credential-gated with no published API reference or downloadable OpenAPI.
  As a large depository institution it is subject to the CFPB Section 1033
  Personal Financial Data Rights rule, but Zions has not published a first-party
  data-access API or a documented FDX-conformant endpoint; consumer-permissioned
  data sharing in practice reaches Zions through third-party aggregators
  (Plaid/MX/Finicity/Akoya) rather than a first-party API surface.
