API / Developer Program

Build on the data layer for human health.

HealthOS is an operating system for biological data: every modality of a human body, continuously measured and connected, with the intelligence layer that makes sense of it. The same platform that powers our app is becoming an API — so researchers, clinicians and builders can work on top of it instead of rebuilding the stack.

What the API exposes

Raw signals

PPG waveforms, continuous glucose, HRV, skin temperature and motion — streamed, timestamped and normalized.

The eight pillars

Glucose, heart, sleep, nutrition, movement, environment, blood pressure and DNA — read through one consistent schema.

Correlations

The discovered relationships between signals — the same engine that surfaces cold × deep sleep or water × body composition.

Lab markers

HbA1c, ApoB, hs-CRP, Lp(a), testosterone, cortisol, Vitamin D and more — read in the context of a personal baseline.

One schema, every signal

Who it’s for

Researchers

Run studies on continuous, multi-modal, real-world biological data at population scale.

Clinicians

See the days between visits — continuous monitoring and one clear signal of what changed.

Builders

Ship health products on top of the data layer instead of rebuilding the sensor stack.

Request early access

We are designing the developer program now and onboarding a first group of research and clinical partners. Tell us what you would build and we will reach out when early access opens.
