# Oura Ring — Data Access

Pull sleep, activity, readiness, heart rate, and other health data from a connected Oura Ring via the Oura Cloud API V2.

**For initial setup (OAuth, app registration, token exchange), see the `oura-setup` skill.**

## Prerequisites

- Oura Ring already connected via OAuth (see `oura-setup` skill)
- Credential stored: `oura` / `access_token` with injection template for `api.ouraring.com` (Authorization header, Bearer prefix)
- Credential ID can be found via `assistant credentials list --search oura` (filter for field `access_token`)

## Making Requests

All requests go through the credential proxy — no need to manually attach tokens.

```bash
curl -s "https://api.ouraring.com/v2/usercollection/{endpoint}?start_date=YYYY-MM-DD&end_date=YYYY-MM-DD"
```

Run via `bash` with:

- `network_mode: "proxied"`
- `credential_ids: ["<oura access_token credential_id>"]`

## Endpoints

| Endpoint             | What It Returns                                                          | Best For               |
| -------------------- | ------------------------------------------------------------------------ | ---------------------- |
| `personal_info`      | Age, weight, height, email                                               | Connection test        |
| `daily_sleep`        | Sleep score, duration, efficiency, stages                                | Morning check-in       |
| `sleep`              | Detailed sleep periods — HR, HRV, movement, timestamps                   | Deep sleep analysis    |
| `daily_readiness`    | Readiness score, HRV balance, recovery index                             | Morning readiness      |
| `daily_activity`     | Steps, calories, movement, MET data, activity score                      | Daily activity summary |
| `heartrate`          | Continuous HR readings (uses `start_datetime`/`end_datetime` ISO format) | Workout HR, resting HR |
| `workout`            | Detected workouts — HR, calories, duration, type                         | Exercise tracking      |
| `daily_spo2`         | Blood oxygen (SpO2) nightly average                                      | Breathing/oxygen       |
| `daily_stress`       | Stress score, recovery periods                                           | Stress monitoring      |
| `ring_configuration` | Ring model, firmware, color, design                                      | Ring info              |

## Query Parameters

- **Most endpoints:** `start_date` and `end_date` in `YYYY-MM-DD` format
- **Heart rate:** Uses `start_datetime` and `end_datetime` in ISO 8601 format (e.g. `2025-01-15T00:00:00-05:00`)
- **Personal info / ring config:** No date params needed
- Omitting dates usually returns recent data (last 1-7 days depending on endpoint)

## Common Patterns

### Morning health check

Pull sleep + readiness + activity for today:

```bash
DATE=$(date +%Y-%m-%d)
curl -s "https://api.ouraring.com/v2/usercollection/daily_sleep?start_date=$DATE&end_date=$DATE"
curl -s "https://api.ouraring.com/v2/usercollection/daily_readiness?start_date=$DATE&end_date=$DATE"
```

### Workout details with HR

```bash
YESTERDAY=$(date -v-1d +%Y-%m-%d)
TODAY=$(date +%Y-%m-%d)
curl -s "https://api.ouraring.com/v2/usercollection/workout?start_date=$YESTERDAY&end_date=$TODAY"
```

### Heart rate during a specific window

```bash
# Adjust the datetime range as needed (ISO 8601 with timezone offset)
curl -s "https://api.ouraring.com/v2/usercollection/heartrate?start_datetime=YYYY-MM-DDT23:00:00-05:00&end_datetime=YYYY-MM-DDT01:00:00-05:00"
```

## Notes

- New rings need **1-2 nights** to calibrate before sleep/readiness scores are meaningful
- Sleep data appears a few hours after waking
- Short workouts (<15 min) may not be auto-detected — check raw heart rate instead
- Heart rate endpoint can return large datasets — keep time windows tight
- Rate limit: 5,000 requests per 5 minutes
- Tokens expire after ~30 days. Refresh using the `oura-setup` skill's token refresh instructions.

## Token Refresh

When the access token expires, use the refresh token via the `oura-setup` skill:

```bash
curl -s -X POST "https://api.ouraring.com/oauth/token" \
  -d "grant_type=refresh_token&refresh_token=REFRESH_TOKEN&client_id=CLIENT_ID&client_secret=CLIENT_SECRET"
```

Store the new access_token and refresh_token. See `oura-setup` for full details.
