Daily sleep scores (0-100) with contributor scores (deep sleep, REM, latency, timing, etc.). Use for "how did I sleep" questions. For bedtimes, sleep stages in minutes, or night heart rate use oura_get_sleep_detail instead. Defaults to the last 7 days.

Per-night sleep sessions: bed and wake times, sleep stages in minutes (deep/REM/light/awake), latency, efficiency, night heart rate, HRV and breathing rate. Also returns bedtime recommendations when Oura has them. Use for "when did I fall asleep", "how much deep sleep", "what was my pulse at night". Defaults to the last 7 days.

Daily readiness scores (0-100) showing how recovered the body is, with contributors (HRV balance, resting heart rate, sleep balance, body temperature) and temperature deviation in °C. Use for "how recovered am I", "should I train today", "is my temperature elevated". Defaults to the last 7 days.

Daily activity: score (0-100), steps, active and total calories. response_format 'detailed' adds minutes by intensity (high/medium/low), sedentary and resting minutes, walking distance. Use for "how many steps", "how active was I", "did I move enough". Defaults to the last 7 days.

Daily stress summary: minutes of high stress, minutes of high recovery, and a day verdict (e.g. 'restored', 'normal', 'stressful'). Use for "how stressed was I", "did I recover today". Defaults to the last 7 days.

Slow-moving health metrics in one call: blood oxygen (SpO2 average % and breathing disturbance index), resilience level (how well the body handles stress long-term), cardiovascular age, and VO2 max. Use for "what is my SpO2 / vascular age / VO2 max / resilience". Sections the ring does not measure come back empty. Defaults to the last 7 days.

Workouts (activity type, intensity, calories, distance, start/end times) plus mind-body sessions (meditation, breathing, relaxation). Use for "how was my run", "did I work out", "did I meditate". Defaults to the last 7 days.

Tags the user logged in the Oura app: caffeine, alcohol, sickness, medication, custom notes, etc. Useful context when explaining why sleep or readiness changed. Read-only: tags can only be created in the Oura app. Defaults to the last 7 days.

Heart rate aggregated per hour (avg/min/max bpm and sample count) across day and night. Use for "what was my pulse today/this afternoon". For sleep-time heart rate prefer oura_get_sleep_detail. Range is capped at 3 days; defaults to the last 24 hours.

User profile (age, biological sex, height in meters, weight in kg) plus ring info: model, size, firmware and current battery level. Use for "how charged is my ring", "what does Oura know about me". Email is never returned.
