Quick Learnings

  • IoT APIs enable near real-time data collection from medical devices, improving patient monitoring and care delivery
  • Medical device API integration connects CGM sensors, blood pressure monitors, pulse oximeters, and other IoT devices to your application
  • Spike IoT API reduces development time by providing standardized connections to medical devices from manufacturers like Freestyle Libre and Dexcom
  • Spike IoT API provides both raw and normalized data formats for flexible integration
  • CGM integration is critical for diabetes management apps, providing continuous glucose readings without device-specific development

The healthcare industry is experiencing a digital transformation driven by connected medical devices. In the US, about 79% of hospitals have adopted telehealth solutions, and the IoT market is expected to reach $13.46 billion by 2028, growing at a 10.20% growth rate. The shift toward connected healthcare is clear.

From continuous glucose monitors to smart patient monitoring systems, IoT APIs are becoming the backbone of modern healthcare applications. Spike IoT API enables developers to connect to medical devices like CGM sensors and blood pressure monitors through a single integration, reducing engineering overhead and improving time-to-market.

What is Spike IoT API?

Spike IoT API serves as the bridge between medical devices and your health and wellness application. Instead of building individual integrations for each device manufacturer, our IoT API provides a unified connection point.

The value becomes clear when you consider the complexity of the medical device landscape. A patient might use a Dexcom CGM, an Omron blood pressure monitor, and a Withings scale. Without an IoT API, you'd need to build three separate integrations, each with different protocols and data formats, not to mention the maintenance. With Spike API integration, you integrate once and access 500+ devices, while we take care of maintaining the APIs.

Why health apps need medical device API integration

Health app users expect seamless data flow between devices and applications. When you connect IoT devices through a unified API like Spike, you enable smoother data syncing and free up developer time to focus on improving user experience and refining core app features. 

Timely monitoring: Users need immediate access to patient or medical data. Spike IoT API delivers this data near real-time to dashboards or analysis tools. 

Reduced development overhead: Building direct integrations with medical device manufacturers is time-consuming and resource draining. Each manufacturer has different APIs and data formats. A unified API eliminates this complexity, letting you focus on your core application features rather than device connectivity and maintenance.

Access to both raw and normalized data: Medical IoT devices from different manufacturers report data in varying formats and structures. Spike IoT API provides access to data in both raw and normalized formats, giving you the flexibility to work with device data to meet your needs. 

Key use cases for IoT APIs in health apps

Remote patient monitoring

Hospitals and clinics use medical device API integration to monitor patients outside clinical settings. Be among the first health applications to integrate several IoT devices, enabling proactive interventions.

Chronic disease management

Build smart health apps for managing heart disease, respiratory conditions, and other chronic illnesses by making sense of continuous data tracking, adding dashboards, and symptom monitoring.

Fitness and wellness apps

Utilize the Spike IoT API to integrate data from over 500 wearables and IoT devices into a unified health tracking experience. Build challenge apps, leaderboards, and personalized workout recommendations powered by heart rate monitors, activity trackers, and recovery metrics.

Digital health coaching

Leverage the Spike IoT API to access biometric data from users' connected devices. Enable AI coaches to provide data-driven guidance based on sleep patterns, cardiovascular metrics, and recovery data.

Corporate wellness programs

Integrate Spike IoT API to track team health metrics across diverse device ecosystems. Run step challenges, monitor health trends, and organise initiatives based on verified activity data while maintaining HIPAA and GDPR compliant data handling.

Why should you choose Spike IoT API? 

Spike offers a scalable, reliable, and secure medical device API integration layer, with several advantages:

  • Data security: HIPAA and GDPR compliant, healthcare-grade data handling ensures your users' sensitive health information remains protected.
  • Dedicated engineering support: each client gets an implementation engineer to help integrate smoothly. 
  • LLM compatible: You can connect data from IoT devices to the Spike MCP layer, enabling AI analytics through an LLM of your choice for personalized AI health insights.
  • Reduced maintenance: Spike takes care of provider API updates with minimal engineering on your side, in some cases reducing support tickets by 40%.

Combine IoT data with AI

Spike IoT API is part of Spike 360° Health Data API, alongside Wearables, Nutrition AI, and Lab Reports APIs, and our MCP layer, creating a unified health data platform.

Spike MCP connects your IoT device data to large language models, enabling AI-powered health insights, without you pre-processing the data. Your LLM of choice can analyze patterns across medical device readings, lab reports, nutrition data, and activity metrics to provide personalized and contextual recommendations.
