Open banking, actually open.
Open banking gives members control of their financial data. Standardized APIs let apps move money, read balances, and share account info — with consent, across institutions, in real time.
This is the architecture. 127 tools, federated access tiers, and every data flow mapped — so you can see exactly how it works before you build on it.
The standard
Financial data
belongs to the member.
Open banking is the principle that people own their financial data — not their bank. Through standardized APIs like FDX (Financial Data Exchange), members authorize third-party apps to access accounts, initiate payments, and aggregate data across institutions.
For credit unions, this means competing on experience rather than lock-in. Members connect to fintech tools they choose. The credit union stays the source of truth — but stops being the bottleneck.
How it works
Consent
Members grant scoped, revocable access to their data. No screen-scraping. No shared passwords. OAuth 2.0 flows with granular permissions.
Standardized APIs
FDX and emerging CFPB 1033 rules define how data moves. Accounts, transactions, balances, identity — all through documented endpoints.
Federation
Credit unions federate access across institutions. Tier 0 is local. Tier 3 spans the network. Same API surface, broader reach.
