Systems and methods for programmatic access of a financial institution system. A normalized API request provided by an application system specifies user information corresponding to at least one account endpoint of an external financial institution system. Responsive to the request, at least one application proxy instance associated with the normalized API request is used to collect transaction information from a corresponding financial institution system by providing the financial institution system with a proprietary API request that specifies at least account credentials associated with the user information. The transaction information is included in at least one proprietary API response provided by the financial institution system. A normalized API response is generated based on the collected transaction information and provided to the application system. Each application proxy instance is constructed to simulate an application of the corresponding financial institution system on behalf of a user associated with the application proxy instance.
