One API for every major wearable on iOS and Android — plus the EU's leading CGM. Vena ingests raw device data, normalizes it to a single clinical-grade model — metrics, workouts, nutrition and menstrual cycle — and serves it as clean JSON or FHIR R4. EU-hosted, GDPR-native.
Honest scope: all major wearables on iOS + Android + the EU's leading CGM — not “500+/99%”.
# Normalized readings, any wearable, one shape curl "https://api.vena.health/v1/readings?from=2026-06-01&to=2026-06-30" \ -H "x-api-key: vena_live_sk_…" # → { # "data": [{ "metric": "hrv", "value": 48.2, # "unit": "ms", "provider": "oura" }], # "count": 412 }
On-device (HealthKit / Health Connect, $0), direct OAuth (Oura, Withings, Polar), or webhook. Anything that syncs to the phone is captured.
Every provider's raw payload maps to one model — hrv, steps, glucose — same name, same unit, whatever the source.
Clean JSON for product, FHIR R4 + LOINC for clinical pipelines. Outbound webhooks push new readings to you.
Per connected user, not opaque credits. You can do the math before you sign.
Data stays in Germany. Real DPA, no SCC gymnastics. Compliance is the product.
iOS + Android on-device ingestion costs almost nothing, so we undercut and still profit.
FHIR R4 / LOINC + longevity-aware metrics, not just raw numbers.
iOS via HealthKit, Android via Health Connect (Apple Watch, Garmin, Samsung, Xiaomi…), direct OAuth for full fidelity, and Abbott FreeStyle Libre via our EU aggregator.
Build the whole integration on a free sandbox, then flip one key to go live. Annual billing = 2 months free.
Free sandbox, real docs, EU-hosted. The API is already in production.
