• Data Monitoring for Mobile Apps: A mobile application developer can query the API to check how much data allowance a user has left for their current billing cycle. This can help users stay informed and avoid unexpected overages, while also offering proactive management options such as data-saving modes.
• Content Streaming Services: Streaming platforms can query the API to check a user’s remaining data volume and adjust the content quality (e.g., reduce video resolution) if the user is nearing their data limit, or preventing them using services that would exhaust their remaining data allowance, such as immersive large events.
