  title: Spike Application User Auth Nutrition AI API
  description: 'Spike (Spike Technologies) unified health and wearables data API. A single integration layer that connects an application to 500+ wearables, IoT devices, CGMs, EMRs, labs, and nutrition sources - Apple Health, Garmin, Fitbit, Oura, Whoop, Dexcom, FreeStyle Libre, Withings, Polar, Suunto, Strava, and more. Applications authenticate their end users with HMAC signatures to mint a JWT access token, connect providers through hosted integration flows, then query normalized health data (sleep, workouts, time series, statistics), analyze nutrition and lab reports, and receive record-change webhooks.


    This document is grounded in Spike''s published OpenAPI (v3.0.2) and public documentation at https://docs.spikeapi.com. Path, method, base URL, auth, and provider surfaces are confirmed from the official OpenAPI. Request and response schemas are modeled generically here where full component schemas were not enumerated - see endpointsModeled notes in review.yml.'
