The rise of intelligent financial platforms driven by innovations in embedded finance, real-time analytics, and API-based service delivery has fundamentally altered the landscape of digital financial ecosystems. However, this transformation has outpaced the development of interoperable and secure interface standards. Existing regulatory frameworks like PSD2 and Open Banking have initiated progress through data-sharing APIs, but practical deployments remain fragmented due to proprietary implementations, incompatible schemas, and insufficient governance across multi-actor environments. This paper addresses the critical gap in interface-level standardization by proposing a novel, layered architecture: the standardized interface framework for intelligent financial platforms (SIFFP). SIFFP integrates acquisition, knowledge, interoperability, intelligent service, and support layers, drawing inspiration from IoT architectural paradigms while tailoring them to the specific demands of financial systems. The framework is validated through a comprehensive proof-of-concept deployment in an e-commerce context, showcasing a working API suite (e.g., /loan/apply, /payment, /risk/analyze) with embedded metadata covering security (OAuth 2.0, mTLS), compliance (ISO 20022, Payment Card Industry Data Security Standard (PCI-DSS)), and schema formats (JSON/XML). Interoperability assessments demonstrate full compatibility with ISO/IEC 19941, and performance benchmarks confirm low-latency transaction processing under concurrent user conditions. Moreover, the work introduces a stakeholder-standards heatmap and standards lifecycle mapping, aligning the framework with pre-standardization best practices and demonstrating its readiness for engagement with formal standards bodies. By bridging theoretical architecture with implementation, SIFFP provides a scalable, extensible, and regulatorily aligned foundation for next-generation financial platforms. This research contributes not only a blueprint for modular financial system design but also a concrete pathway to de facto and formal standard development, laying the groundwork for future interoperability in embedded lending, insurance, and open finance ecosystems.
