API Economy

An economic system in which growth and value creation are driven primarily by the production, distribution, and application of knowledge and information rather than physical goods. In the knowledge economy, intangible assets — including human capital, software, data, and intellectual property — constitute the majority of enterprise and national wealth.

The ability of different information technology systems, software applications, and data formats to communicate, exchange data, and use the information that has been exchanged effectively. Interoperability is a critical design requirement in open banking, healthcare IT, and enterprise software, and is increasingly mandated by regulation.

An umbrella term for the broad range of services delivered over the internet on a subscription basis, encompassing Software as a Service, Platform as a Service, Infrastructure as a Service, and numerous specialised variants. XaaS business models convert capital expenditure into operating expenditure for customers and derive the majority of their enterprise value from intangible assets including recurring customer relationships, proprietary platforms, and data.

Intangible assets that exist in digital form and contribute to business value, including software platforms, mobile applications, websites, digital content libraries, algorithms, and automated workflows. Digital assets are increasingly the primary value drivers in modern businesses.

The EU directive (2015/2366) that regulates payment services and payment service providers, mandating strong customer authentication, open banking through account access APIs (XS2A), and enhanced consumer protection. PSD2 has fundamentally reshaped the European payments landscape by requiring banks to provide licensed third parties with access to customer account data and payment initiation capabilities.

A virtual representation of a physical asset, process, or entire business operation that uses real-time data and simulation to mirror its real-world counterpart. Digital twins enable predictive maintenance, scenario modelling, and operational optimisation.

A centralised platform for storing, managing, and serving the engineered features (input variables) used by machine learning models in both training and real-time inference. Feature stores ensure consistency between training and production environments, enable feature reuse across multiple ML models, reduce duplication of feature engineering effort, and provide a governance layer for tracking feature lineage and ownership.

A self-executing program stored on a blockchain that automatically enforces the terms of an agreement when predetermined conditions are met, without requiring intermediaries. Smart contracts enable trustless transactions, automated escrow, decentralised finance protocols, and programmable business logic.
