Developer API · Now in sandbox

The only clinical AI
that remembers your patient.

Nera fuses ECG, glucose, BP, HRV, and sleep across days and weeks — not just today's snapshot. The risk score gets more accurate the longer you use it. No other API does this.

What you can build

Longitudinal. Multimodal.
Deterministic.

Other APIs score a snapshot. Nera accumulates your patient's full history — ECG, glucose, BP, HRV, sleep — and fuses them into a single risk picture that gets sharper over time. Trained on 12 million real patient records. Same inputs always produce the same output — auditable, reproducible, clinically defensible.

POST /b2b/ecg/analyze

ECG Analysis

Photo of a paper ECG.
Full clinical diagnosis.

Upload a phone photo of any paper ECG report. Nera returns rhythm, STEMI detection, QTc/PR/QRS intervals, and a clinical interpretation — fused with the patient's longitudinal vitals context. Trained on 12M ECG records.

94% AFib detection accuracy across 12M ECGs

STEMI flagging with lead-level detail

12-lead and single-lead supported

POST /nera-api/vitals/risk-score

Longitudinal Risk Score

Scores that learn.
Not just today's reading.

Log daily vitals per patient. Nera builds a full longitudinal profile — fusing HR, HRV, BP, glucose, SpO2, and sleep across weeks — and returns a 0–100 risk score grounded in the patient's entire history. A single OpenAI call cannot do this.

HR, HRV, SpO2, BP, glucose, HbA1c, BMI

Age-adjusted clinical thresholds

Plain-language narrative for non-clinicians

POST /nera-api/glucose/estimate

Multimodal Glucose

Continuous monitoring.
No needles required.

Any wearable PPG signal → estimated glucose range in mg/dL. Nera's proprietary multimodal algorithm fuses optical and physiological signals internally — not a single-sensor lookup. Activity-corrected, stress-corrected, calibrated on 12M paired glucometer readings.

Works with any reflectance PPG sensor

Activity & stress physiological corrections

Confidence zone: normal / pre-diabetic / diabetic

POST /nera-api/report/generate

Longitudinal Reports

30-day narrative.
Written by Nera AI.

Send a patient's daily vitals history. Receive a structured clinical narrative — trends across all signals, the single most important pattern, follow-up priority, and recommendations. EMR-ready. Impossible to produce from a single-day snapshot.

AI-generated clinical narrative

7–30 day trend analysis included

Follow-up priority flag: immediate / 7d / 30d
