UltraSignal Sensor Platform API is one of 4 APIs that [Ultrahuman](https://apis.io/providers/ultrahuman/) publishes on the [APIs.io](https://apis.io/) network. Tagged areas include UltraSignal, Sensors, PPG, Accelerometer, and Developer Platform. The published artifact set on APIs.io includes API documentation.

UltraSignal is Ultrahuman's wearable developer platform for building custom algorithms on raw Ring AIR sensor streams - photoplethysmography (PPG), temperature, and accelerometer data. Access is application-gated with a loaned developer kit; priority goes to apps that leverage the ring's sensors. No public endpoint contract is documented, so this API is listed for discovery without modeled endpoints.
