The BMI Information Fetcher API offers a comprehensive analysis of a person's physical and metabolic status based on basic body measurements. This API uses parameters such as weight, height, waist, hips, neck, age, gender, and physical activity level to generate a wide range of health indicators, delivering results in different systems of units, such as metric or imperial.
Its main function is to calculate Body Mass Index (BMI), a standard indicator that classifies an individual's weight status (underweight, normal, overweight, or different degrees of obesity). However, the API goes far beyond BMI, integrating complementary metrics that allow for a more accurate and personalized assessment of physical well-being.
Overall, the BMI Information Fetcher API is a comprehensive solution for users looking to integrate a reliable body assessment system into their applications or platforms, with multilingual support and clear, practical, interpretive results based on scientifically validated formulas.
Processes body measurements and returns BMI, body fat, metabolism, risks, and detailed metrics.

The BMI Calculation endpoint returns a comprehensive set of health indicators, including BMI, body fat percentage, basal metabolic rate (BMR), total daily energy expenditure (TDEE), waist-to-hip ratio (WHR), waist-to-height ratio (WHtR), and ideal weight range, among others.
Key fields in the response include "bmi" (value, category, risk), "body_fat" (value, method), "bmr" (value, formula), "tdee" (value, activity level), and "ideal_weight" (min, max). Each field provides critical insights into an individual's health status.
Users can input parameters such as weight, height, waist, hips, neck, age, gender, and physical activity level to customize their health assessment and receive tailored results.
The response data is structured in a JSON format, with nested objects for specific metrics like BMI and body fat. Each metric includes relevant values and categories, making it easy to parse and utilize in applications.
The API utilizes scientifically validated formulas and methods, such as the Mifflin-St Jeor equation for BMR and the US Navy method for body fat calculation, ensuring high accuracy and reliability in the results.
Data accuracy is maintained through the use of scientifically validated formulas for calculations, such as the Mifflin-St Jeor equation for BMR and the US Navy method for body fat estimation, ensuring reliable results.
Typical use cases include health and fitness applications, personalized wellness programs, and medical assessments, where users can track and analyze their physical and metabolic health indicators.
For example, "bmi.category" indicates weight status (e.g., "Overweight"), while "bmr.value" shows the daily calorie requirement at rest. Understanding these fields helps users interpret their health metrics effectively.
Users can leverage the returned data to monitor health trends, set fitness goals, and make informed lifestyle choices based on their BMI, body fat percentage, and other metrics provided in the response.
Users can expect consistent data patterns, such as BMI categories (underweight, normal, overweight, obesity) and risk assessments (e.g., increased cardiometabolic risk), which help in interpreting health status effectively.

To obtain your API key, you first need to sign in to your account and subscribe to the API you want to use. Once subscribed, go to your Profile, open the Subscription section, and select the specific API. Your API key will be available there and can be used to authenticate your requests.
You can’t switch APIs during the free trial. If you subscribe to a different API, your trial will end and the new subscription will start as a paid plan.
If you don’t cancel before the 7th day, your free trial will end automatically and your subscription will switch to a paid plan under the same plan you originally subscribed to, meaning you will be charged and gain access to the API calls included in that plan.
The free trial ends when you reach 50 API requests or after 7 days, whichever comes first.
No, the free trial is available only once, so we recommend using it on the API that interests you the most. Most of our APIs offer a free trial, but some may not include this option.
Yes, we offer a 7-day free trial that allows you to make up to 50 API calls at no cost, so you can test our APIs without any commitment.
Zyla API Hub is like a big store for APIs, where you can find thousands of them all in one place. We also offer dedicated support and real-time monitoring of all APIs. Once you sign up, you can pick and choose which APIs you want to use. Just remember, each API needs its own subscription. But if you subscribe to multiple ones, you'll use the same key for all of them, making things easier for you.
