The Definitive Human Design API
Calculate the complete Human Design bodygraph from a single POST request. Get exact center definitions, active gates, profile, and incarnation cross with sub-arcsecond NASA JPL precision.
The API for Human Design Apps
Complete Bodygraph Data
Calculate all 9 centers, 64 gates, and 36 channels with exact definition states and planetary activations for both Personality and Design.
Core Mechanics
Instantly retrieve the user's Type, Strategy, Inner Authority, Profile (e.g. 3/5), and Incarnation Cross.
Deep Detail
Includes line activations for every gate, color, tone, and base calculations for advanced PHS (Primary Health System) and psychology.
JPL Precision
Unlike generic libraries, our Human Design engine calculates the exact moment the Sun was 88° behind the natal position using NASA JPL data.
