+# API Proposal 
+
+
+### API family name  
+V2X Exposure API (Not Finalized)
+
+### API family owner  
+X Flow Software Technology LLC
+
+### API summary  
+The V2X Exposure API aims to expose Vehicle-to-Everything (V2X) capabilities to application developers through standardized CAMARA network APIs. The proposal leverages ETSI MEC V2X Information Service APIs and introduces a simplified CAMARA abstraction layer that hides underlying network and radio complexity.
+
+The API enables applications to interact with vehicles, infrastructure, and edge platforms through operator-exposed APIs.
+
+Example business cases:
+
+Connected Ambulance Routing – Emergency vehicles receive hazard notifications and optimized routes through edge and network intelligence.
+
+Collision Risk Detection – Nearby vehicles and vulnerable road users receive alerts based on real-time traffic and infrastructure data.
+
+Smart City Mobility Services – Applications access V2X provisioning information and safety messages for traffic management and road safety.
+
+### Technical viability  
+The proposed API relies on existing and standardized technologies:
+
+ETSI MEC V2X Information Service (MEC 030) for localized V2X interactions between vehicles, infrastructure, and MEC applications.
+
+ETSI MEC platform for edge computing and low-latency service execution.
+
+CAMARA Network APIs to expose simplified northbound APIs for developers.
+
+A Transformation Function (TF) can map MEC southbound APIs to CAMARA northbound service APIs.
+
+Relevant supporting standards:
+
+ETSI MEC specifications (including V2X Information Service)
+
+CAMARA API framework
+
+ETSI MEC White Paper No. 68 (MEC application developer guidelines)
+
+These technologies are already standardized and widely adopted in 5G and edge computing environments.
+
+### Commercial viability  
+The proposed API builds on existing edge computing and MEC-based deployments developed within ongoing smart mobility and smart city projects.
+
+Relevant projects include:
+
+CASCAD-e Project – Demonstrates connected ambulance services using edge computing, enabling real-time hazard notifications, remote medical triage, and secure transmission of patient data.
+
+ToMOVE Project – ToMOVE Project – Provides an edge cloud platform with an API Gateway and ETSI-compliant MEC infrastructure, supporting smart mobility services like in City of Turin and V2X communication use cases using smart city datasets and infrastructure.
+
+These projects demonstrate the feasibility of deploying V2X services using MEC platforms and API exposure layers, which can be extended with CAMARA APIs to provide standardized developer access.
