Oura Ring API
Provides access to Oura Ring biometric data including sleep stages, HRV, body temperature, SpO2, activity, and readiness scores for health analytics and wellness automation.
Score Breakdown
⚙ Agent Friendliness
🔒 Security
Granular OAuth scopes per biometric data category enable least-privilege access. PAT support is convenient but introduces long-lived credential risk if not stored securely. GDPR compliance with EU data residency option is important for European health data.
⚡ Reliability
Best When
Building personalized health coaching, sleep optimization, or longitudinal wellness analytics tools for users who own an Oura Ring and have granted OAuth or PAT access.
Avoid When
You need sub-minute data freshness, are building for non-Oura device owners, or require regulatory-grade medical data provenance.
Use Cases
- • Pull nightly sleep stage breakdowns and HRV data to build a longitudinal recovery trend dashboard for athletes
- • Fetch daily readiness scores to dynamically adjust a workout recommendation agent's intensity suggestions
- • Monitor continuous body temperature trends to detect early illness signals and surface alerts to a health monitoring agent
- • Aggregate activity and sleep data across a wellness program cohort to generate weekly population health summaries
- • Correlate SpO2 and sleep quality metrics with logged lifestyle variables to identify patterns in a personal health journal agent
Not For
- • Real-time physiological monitoring with latency under a minute — data is synced periodically, not streamed continuously
- • Applications targeting non-Oura wearable users — the API is device-specific and has no cross-device abstraction
- • Clinical diagnostic workflows requiring FDA-cleared data pipelines — Oura is a consumer wellness device, not a medical device
Interface
Authentication
Supports OAuth 2.0 authorization code flow for multi-user applications with scopes per data category (daily.sleep, daily.activity, daily.readiness, heartrate, etc.) and Personal Access Tokens for single-user or development use. PATs are available immediately via the Oura cloud dashboard with no partner approval required. OAuth apps require registration but approval is generally accessible.
Pricing
Personal API access (PAT) is free for device owners. Building a commercial product serving many users requires an Oura enterprise agreement.
Agent Metadata
Known Gotchas
- ⚠ Data for a given day may not be finalized until several hours after midnight — fetching today's sleep data before noon may return incomplete or absent records
- ⚠ The ring must be worn and synced via the Oura app for data to appear; agents should handle empty responses gracefully without treating them as errors
- ⚠ PAT credentials are tied to a single user and do not expire by default — agents must handle revocation scenarios where a PAT is deleted by the user
- ⚠ Webhook payloads contain only event type and user ID, not the actual data — agents must make a follow-up API call to retrieve updated records
- ⚠ Some metrics (e.g., SpO2 nightly average) are only available for Oura Generation 3 rings — agents should check device generation before expecting certain endpoints to return data
