Open API Regulation Explained: Meaning, Types, Use Cases, and Risks

In plain language, it is the legal and operational backbone of open banking and, increasingly, open finance. It matters because it changes who can access financial data, how customers give permission, how firms compete, and how regulators balance innovation with privacy, security, and consumer protection.
