MX Technologies is a privately held financial data platform headquartered in Lehi, Utah, operating as a B2B data aggregator and open-finance infrastructure provider — not a chartered bank or credit union. MX connects consumer and business accounts across tens of thousands of financial institutions and fintechs, then cleanses, categorizes, and enhances that data so banks and fintechs can build verification, aggregation, and personal-finance experiences. It is one of the major US open-finance aggregators alongside Plaid, Finicity, and Akoya.
Unlike most US banks, MX runs a real, self-documented developer surface with downloadable OpenAPI 3.0 specifications published at docs.mx.com.

- Data Sharing
Data Access is MX's open-finance API platform for sharing an institution's financial data and accessing other institutions' data using FDX and OAuth standards, with tokenized, consumer-permissioned access that consumers can grant, modify, and revoke at any time.

- Data Access
MX documents FDX participation directly: its Data Access product "enables you to share your institution's financial data and access the data of other institutions using FDX and OAuth standards." No CFPB Section 1033 statement was found on the public site as of the review date. MX is an aggregator, so much US bank data flows through MX rather than through those banks' own first-party APIs.
