Core offering

BIAN provides a vendor-neutral, open banking architecture framework consisting of the Service Landscape (320+ Service Domains, 5,000+ service definitions) and 250+ Semantic APIs that standardize how banks and software vendors define and integrate banking capabilities. The framework is delivered through the BIAN Portal, complemented by the Coreless Banking microservices platform, AI-powered tools (API Align, BIAN Chat, Agentic Banking Studio), training and certification programs, and a member Marketplace. The offering enables banks to reduce integration costs, modernize legacy core systems, and achieve plug-and-play interoperability across vendors.

BIAN (Banking Industry Architecture Network) is an independent not-for-profit standards association that provides a unified banking technology framework. The core product portfolio centers on the Service Landscape (a reference framework of 320+ Service Domains organizing all bank activities) and the BIAN Portal (home to 250 APIs and more than 5,000 service domains). Key platform tools include Business Scenario Designer for workflow development, API Align for API mapping and certification scoring, BIAN Chat for AI-powered Q&A, and the Agentic Banking Studio for transforming concepts into AI-powered systems. The Coreless Banking initiative provides a microservices infrastructure platform for banks to achieve interoperability without legacy constraints. BIAN supplements its core standards with training programs (Foundation, Banking Architecture, Data Architecture), certification levels (Foundation Certification and Architecture Practitioner Certification), and a Marketplace for member-provided offerings.
