Here is a reworked README.md that accurately reflects your project’s current state and objective as a Financial Data Aggregator prototype using Plaid Link and FDX APIs to simulate a Data Out use case.
This version is concise, professional, and tailored to your architecture and goals.

FDA_V2 is a prototype web application and API server that demonstrates a Data Out use case for open banking.
It enables a customer to link their bank account using Plaid Link and then retrieve their financial data—including contact, account, transaction, and statement information—via FDX-aligned APIs.

The goal is to simulate a modern, standards-based data sharing experience, showing how a consumer can control and export their financial data to third-party applications using industry protocols.

• Plaid Link Integration:
  Customers can securely link their bank accounts using the Plaid Link widget.

• FDX-Aligned API Endpoints:
  Simulates a provider-side Financial Data Exchange (FDX) API, returning customer, account, transaction, and statement data in FDX format.

• Professional Web UI:
  Responsive, Fidelity-branded dashboard for linking accounts and viewing retrieved data.

• Data Out Simulation:
  Models the consumer experience of exporting their financial data to an external app or aggregator.

• Node.js/Express Backend:
  RESTful API server with modular code, SQLite database, and clear separation of UI and API logic.

• Node.js (v16 or later)
• npm
• SQLite3 (for local database)

1. Clone the repository:

   git clone https://github.com/jryan99/FDA_V2.git
   cd FDA_V2

2. Install dependencies:

   npm install

3. Set up the database:

   • Ensure fdx.db exists, or run the provided SQL scripts to initialize the schema.

4. Start the API server:

   node fdx-api.js

   • The server will be available at http://localhost:3000 (or your configured port).

• Web UI:
  Open http://localhost:3000/public/index.html in your browser to use the Fidelity-style dashboard and simulate account linking and data retrieval.

• API Endpoints:
  Use REST endpoints to retrieve FDX-format data:

  • GET /api/openbank/customer/:customerId
  • GET /api/openbank/accounts?customerId=...
  • GET /api/openbank/transactions?customerId=...
  • GET /api/openbank/statements?customerId=...

• Plaid Link:
  The UI will launch Plaid Link for simulated account linking.
  (Configure your Plaid sandbox credentials in the environment as needed.)

• All source code is in the project root and public/ directory.
• Modify fdx-api.js, main.js, and style.css to extend or customize functionality.
• Static assets (HTML, JS, CSS) are served from the public/ directory.

This project demonstrates how a financial institution or fintech can implement a Data Out solution using Plaid Link for account authentication and FDX APIs for secure, standards-based data sharing.
It is intended for prototyping, demonstration, and educational purposes in the context of open banking and consumer data rights.
