Face-to-BMI Analysis API

Face-to-BMI Analysis API

Arya.ai’s Face-to-BMI API lets you estimate a person’s Body Mass Index (BMI), age, and gender using only a facial image. This AI-powered solution is designed for health platforms, fitness apps, insurance firms, and remote wellness tracking tools.
Face-to-BMI Analysis API

The Face-to-BMI API leverages facial biometrics and deep learning to detect physical traits like age, gender, and body fat indicators correlating with BMI. It provides an accurate health estimation without needing physical instruments.

  • Image-only input – no weight or height needed

This API supports use cases where physical health data needs to be estimated remotely or in real time:

  • Digital Health & Wellness Apps
  • Telemedicine Platforms
  • Insurance Risk Scoring
  • Corporate Wellness Programs
  • Fitness Coaching Solutions
  1. Upload a clear facial photo of the user
  2. AI model detects face and analyzes geometry
  3. Returns estimated BMI, age, and gender in real-time
  • Input: JPEG or PNG face image
  • Output: Structured JSON with BMI, age range, and gender prediction

A Comprehensive Guide

Everything You Need to Know About Face-to-BMI Analysis API

The Face-to-BMI API is a cutting-edge solution transforming how wellness and health data is captured—no more manual inputs or physical tools. Instead, a user simply uploads a selfie and, within seconds, receives insights into their estimated BMI, gender, and age.

This breakthrough API opens the door to contactless health profiling for industries that want to deliver intelligent, non-intrusive assessments, especially when in-person evaluation isn’t feasible.

How It Works in Detail

  1. User Upload: The user provides a selfie or face photo.
  2. Facial Detection: The API detects facial landmarks (eyes, nose, jawline, etc.).
  3. Feature Extraction: Facial metrics such as width, symmetry, skin tone, and face ratio are analyzed.
  4. AI Analysis: Using a trained model on thousands of BMI-tagged facial images, the system compares the user’s facial geometry to estimate a likely BMI range.
  5. Demographic Detection: Age and gender are also inferred using deep learning models trained on verified datasets.
  6. Result Delivery: The API responds with structured data—ideal for dashboards, apps, and reports.

Why Facial-Based BMI Estimation Matters

  • No Physical Devices Needed: Ideal for remote assessments.
  • Frictionless UX: One image replaces lengthy questionnaires.
  • AI-Powered Insight: Based on extensive and diverse datasets.
  • Scalable: It can handle thousands of face-based health checks daily.

Feature Summary

  • Estimate BMI range using only a face photo
  • Return estimated gender and age bracket
  • No weight/height entry required
  • Results in <2 seconds per image
  • Easily embedded into web/mobile platforms
