Build contactless vital sign workflows with Web, React, native mobile, embed widget, headless SDK, or REST integrations. SDKs manage camera access, scan guidance, payload preparation, secure upload, polling, and cleanup.

onProgress: (event) => updateProgress(event.percent),

});
const result = await sdk.measureVitals({

});Each path uses the same core session model while giving your team the right UI control, platform support, and deployment shape.

X-API-Key: ck_live_your_key_heremeasureVitals({ videoElement })Use SDK capture, scan-quality callbacks, secure upload, and polling while rendering your own camera and results interface.
Install / Access
Use your own preview, overlays, and result UIThe SDK performs local capture, scan quality checks, and measurement payload preparation before secure processing. The low-level payload format is private and can change between SDK versions.
The SDK opens the camera with permission, guides scan readiness, and checks lighting, motion, pose, and face position.
The SDK prepares a secure measurement payload locally. The standard flow does not upload raw video, raw frames, or photos.
The SDK uploads the prepared payload and Circadify returns configured vital sign outputs through the API.
Your app receives structured results with confidence context. Circadify does not retain results by default.
BPM result with confidence context.
Returned as supported HRV metrics for the scan.
Breaths per minute when scan quality is sufficient.
Systolic and diastolic trend outputs when enabled.
Blood oxygen signal when enabled for the deployment.
Derived signals when supported by the configuration.
