Understanding Network APIs

A Network API (Application Programming Interface) enables applications and services to ‘talk’ to the network, directly accessing mobile network capabilities to perform tasks such as verifying users’ identity, location, or ensuring quality of service. They allow the intelligence inside mobile networks to become accessible, at scale, through a single interface. APIs are the “invisible engines” that make the digital services we rely on everyday function.  

Yes, operator-by-operator integration is technically possible – but commercially impractical at scale. Each operator historically exposed capabilities differently, requiring separate negotiation, integration, and maintenance. This fragmentation has been the single biggest barrier to enterprises unlocking the value of mobile network capabilities. 

The most commercially deployed APIs to date fall into three broad categories: 

• Fraud prevention and identity: Number Verification, SIM Swap detection, Know Your Customer (KYC) Match, and Silent Authentication allow banks, e-commerce platforms, and digital services to verify users’ identities in real time.
• Quality on Demand (QoD): Applications can request enhanced or guaranteed network performance for specific use cases — online payments, video streaming, autonomous vehicle safety, drone operations, or AR/VR — without infrastructure investment.  
• Location and mobility: Device location verification, geofencing, and edge discovery APIs allow applications to optimise performance dynamically, opening opportunities in logistics, field services, and connected vehicles. 

Research from McKinsey estimates that network API initiatives could unlock an additional $300 billion market opportunity by 2030 for the telecommunications industry and the businesses that build on it. 

For enterprises, the risk of inaction is competitive disadvantage. Organisations that integrate standardised network APIs into their products and services will be able to offer capabilities that their competitors relying on legacy approaches simply cannot match.  

GSMA Open Gateway is a global initiative to transform mobile networks into a platform of standardised, easily consumable APIs for developers, enterprises, and cloud providers. The technical specifications underpinning it are developed through CAMARA, an open-source, vendor-neutral project hosted by the Linux Foundation. GSMA Fusion provides a framework for enterprise to work with developers and carriers to develop and tailor standard APIs to address specific use cases. 

• Assess where network capabilities create value: Identify use cases that reduce cost, improve customer experience, or create new revenue. 
• Engage with Open Gateway channel partners: A growing ecosystem of 43 aggregator partners now bridges operator APIs and enterprise demand. These partners simplify access and accelerate time-to-value without requiring direct operator relationships. 
• Build on open standards from the start: Proprietary integrations with individual operators create technical debt and limit scalability. CAMARA-standardised APIs ensure your investment is future-proof. 
• Treat network APIs as a security asset: Open, standardised network APIs are essential infrastructure for the emerging agentic AI ecosystem. Organisations that embed network-level fraud prevention now will be better positioned as AI-driven threats escalate.
