description: Ultrahuman makes the Ring AIR and Ring Pro smart rings and the M1 continuous glucose monitor (CGM), a subscription-free
  metabolic-health wearable ecosystem. Its Partner (UltraSignal) API lets approved partners read user-consented health metrics
  - sleep, HRV, resting heart rate, skin temperature, SpO2, movement/recovery indexes, VO2 max, and (with the M1 patch) continuous
  glucose - over an OAuth 2.0-secured REST API. A separate UltraSignal developer program offers raw sensor streams (PPG, temperature,
  accelerometer) from the Ring AIR via a loaned developer kit. API access is not self-serve - partners apply and are onboarded
  with client credentials; end users authorize data sharing from the Ultrahuman app.

  description: Reads user-consented Ring AIR / Ring Pro daily metrics via the ring_data scope - sleep stages, duration, efficiency
    and sleep score, HRV (rMSSD), resting and night heart rate, skin temperature deviation, SpO2, steps, movement index, recovery
    index/score, metabolic score, and VO2 max. GET by date (YYYY-MM-DD) or by a start/end epoch window (max 7 days). Endpoint
    paths are documented in the partner developer docs; request/response shapes here are modeled from the docs.

  description: Reads continuous glucose data via the cgm_data scope, for users with an active Ultrahuman M1 CGM patch - individual
    readings (mg/dL, ~5-minute cadence), average glucose, glucose variability, estimated HbA1c, and time-in-target-range percentage.
    Surfaced through the same metrics endpoint, gated on the cgm_data scope. Available only when a user has an active patch.

  description: 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.
